Abstract: " Patterns of body size and net construction suggest that current speed and food-particle concentration (not size) influence the distribution of suspension-feeding caddisflies on a downstream gradient. Large ancestral taxa with high filtration rates occur in resource-poor upstream habitats; more derived members of the phylogeny enter successively in downstream reaches with slower current and greater concentrations of particulate food.

SUMMARY: "The stream fauna of the upper Clearwater Creek drainage was almost eliminated by the lateral blast and associated deposits of tephra and organic debris from the 1980 eruption of Mt. St. Helens. Although 37 species have been recorded in benthic collections, the density of caddisflies in 1985 was only 30 m-2. Light-trap collections of adults for nine nights between July and September 1985 were compared for a site on Clearwater Creek, in the blast zone, and on a tributary where the riparian vegetation remained intact. More than 3,400 adults were collected and 55% of these were from the Clearwater Creek site. Of the 69 species identified, 45 were taken at Clearwater Creek and 56 at the Forested Tributary ; 33 species were common to both sites. Based on both the diversity and abundance of adults, it is apparent that low density of the benthic caddisfly fauna cannot be attributed to a lack of colonizing adults."

Abstract: "Lactic acid as a macerating agent for preparing Trichoptera genitalia has several advantages over traditional methods, including the greater likelihood of causing the endotheca of the phallus to evert and also the more complete extension of pleated or glandular structures. The value of doing this is that these characters are useful in making taxonomic and phylogenetic assessments."

Abstract: "Climate change poses a considerable threat to the biodiversity of high latitude and altitude ecosystems, with alpine regions across the world already showing responses to warming. However, despite probable hydrological change as alpine glaciers and snowpacks shrink, links between alpine stream biota and reduced meltwater input are virtually unknown. Using data from the French Pyrénées, we demonstrate that taxonomic richness and total abundance of stream macroinvertebrates increase significantly as meltwater (snow melt and glacier melt) contributions to river flow decrease. Macroinvertebrate species showed a gradation of optimum meltwater conditions at which they persist. For example: Habroleptoides berthelemyi (Ephemeroptera), Perla grandis (Plecoptera) and Rhithrogena spp. (Ephemeroptera) increased in abundance when meltwater contributions to streamflow decrease, whereas in contrast, Rhyacophila angelieri (Trichoptera) and Diamesa latitarsis spp. (Diptera) decreased in abundance. Changes in alpine stream macroinvertebrate community composition as meltwater contributions decline were associated with lower suspended sediment concentration, and higher water temperature, electrical conductivity and pH. Our results suggest α diversity (at a site) of streams presently fed by meltwaters will increase with future meltwater reductions. However, β diversity (between-sites) will be reduced as snow melt and glacier melt decrease because the habitat heterogeneity associated with spatiotemporal variability of water source contributions will become lower as meltwater contributions decline. Extinction of some endemic alpine aquatic species (such as the Pyrenean caddis fly R. angelieri) is predicted with reduced meltwater inputs, leading to decreases in γ diversity (region). Our identification of significant links between meltwater production and stream macroinvertebrate biodiversity has wider implications for the conservation of alpine river ecosystems under scenarios of climate change induced glacier and snowpack loss."

They studied Trout Creek where it runs through the Edna Coal Mine in northwestern Colorado. The mine spoils were 30 meters from the edge of the creek (approximately a 100 foot buffer zone). They found the aquatic insect density (numbers per square meter) and biomass (weight in grams per square meter) did not change above and below the mine. The Shannon-Weaver Diversity index also showed no difference between sites. However the community structure (which species were present and proportions) did change. Since there were irrigation water and cattle influences at their downstream site, their results may reflect these additional water uses. They note the biggest visible change at this mine is the loss of willow and alder trees downstream of the mine. The caddisfly population changed the most between sites, shifting from a mix of families above the mine to dominance by Hydropsychidae and Glossosomatidae below the mine.

At Lake Hazen, Ellesmere Island, Canada (71;° 18´ W., 81° 49´ N.), where females comprise about 96% of active adults, a nulliparous individual in captivity laid 98 eggs, of which 91 hatched. Her receptaculum seminis was empty. The likelihood that this female had exhausted an endowment of sperm on one egg-batch, which nevertheless showed high viability, is extremely small."

Djernæs,M 2011 Structure and phylogenetic significance of the sternum V glands in Trichoptera. Zootaxa 2884: 1-60. PDF
The sternum V gland usually produces sex pheremones in some female caddisflies and butterflies. Gland function in male insects is unclear and may be used for aggregation or defense.
Abstract: "I investigated the sternum V gland in 38 families of Trichoptera, and found it to be present in 25 of these. I found that the gland is generally present in Annulipalpia, except Dipseudopsidae, and in Spicipalpia. It is widespread in Plenitentoria, while it is often absent in Brevitentoria, especially in males. The opening is slit-like and U or crescent-shaped. There is significant variation in the cuticular structures associated with the opening ranging from no apparent modification, over scaly patches to elaborate protuberances. Gland opening muscles are associated with the gland in all families except Psychomyiidae, and are divided into 2 distinct types: One originating on the front edge of sternum VI found in Philopotamidae, Rhyacophilidae, Glossosomatidae and Hydroptilidae; and 1 originating on the cuticle of sternum V found in all other trichopterans. The shape of the gland reservoir is variable, from round periform to reniform, elongate or compartmentalised. Muscle fibres are often associated with the reservoir, but are notably absent in Limnephilidae. I mapped characters based on gland structures on a phylogeny of Trichoptera, and discuss the results. The sternum V gland provides potentially important characters from the superorder to the species level. I discuss 2 cases where characters from the sternum V gland may solve existing phylogenetic and taxonomic puzzles: Delimitation of Dipseudopsidae versus Polycentropodidae and the relationships among the hydropsychid subfamilies. "

Abstract: The sternum V glands are a key synapomorphy that unites Trichoptera with Lepidoptera, but their functional aspects have not been analysed from an evolutionary perspective. We examine phylogenetic trends and correlations between chemical and morphological features of these glands. The most likely ancestral gland compounds are heptan-2-ol, 4-hepten-2-one and -ol, nonan-2-one, and 6-nonen-2-one and -ol, making pheromone production a plausible ancestral function. The most widespread gland compounds (heptan-2-one and -ol and nonan-2-one and -ol) are not known from Apataniidae + Limnephilidae (Trichoptera), which in turn uniquely produce a number of methylated 3-ketones and their corresponding alcohols, probably functioning as pheromones. We propose a functional connection between perforated patches on sternum IV in females and a scaly/dome-covered area around the gland openings, as well as between perforated patches and lack of Trichoptera-type opening muscles. We also propose a functional connection between the shape of the gland reservoirs and the presence of gland reservoir musculature. The perforated patches were significantly correlated with several gland compounds that had double bonds between carbon atoms: the double bonds may lower the viscosity of the compounds, facilitating secretion through the tiny pores of the perforated patches. The production of defensive substances in Pycnopsyche (Trichoptera: Limnephilidae) is probably connected to the presence of large, compartmentalized gland reservoirs. Large glands in male Hydropsyche (Trichoptera: Hydropsychidae) are probably linked to male aggregation pheromone production. The relative sizes of sternum V gland reservoirs and fenestral gland reservoirs in female philopotamids (Trichoptera) suggest a complementary function of the two structures.

Abstract: " Eggs of bullhead (Cottus gobio) were found with damaged shells and with the contents removed. Experiments in laboratory aquaria indicated that the damage was caused by caddis larvae and that the type of caddis involved in egg predation might be identified by the nature of the shell damage. "
We don't have bullheads in Gunnison County, but trout and caddisflies could possibly have similar interactions.

Abstract: "Mitochondrial genomes have been widely used for phylogenetic reconstruction and evolutionary analysis in various groups of Insecta. Gene rearrangements in the mitogenome can be informative characters for phylogenetic reconstruction and adaptive evolution. Trichoptera is one of the most important groups of aquatic insects. Prior to this study, complete mitogenomes from Trichoptera were restricted to eight families, resulting in a biased view of their mitogenome structure and evolution. Here, we assemble new mitogenomes for 66 species by high-throughput sequencing. The mitogenomes of 19 families and 47 genera are documented for the first time. Combined with 16 previously published mitogenomes of Trichoptera, we find 14 kinds of gene rearrangement patterns novel for Trichoptera, including rearrangement of protein-coding genes, tRNAs and control regions. Simultaneously, we provide evidence for the occurrence of tandem duplication and non-random loss events in the mitogenomes of three families. Phylogenetic analyses show that Hydroptilidae was recovered as a sister group to Annulipalpia. The increased nucleotide substitution rate and adaptive evolution may have affected the mitochondrial gene rearrangements in Trichoptera.

Abstract: " Gene rearrangement of the mitochondrial genome of insects, especially the rearrangement of protein-coding genes, has long been a hot topic for entomologists. Although mitochondrial gene rearrangement is common within Annulipalpia, protein-coding gene rearrangement is relatively rare. As the largest family in Annulipalpia, the available mitogenomes from Hydropsychidae Curtis, 1835 are scarce, and thus restrict our interpretation of the mitogenome characteristic. In this study, we obtained 19 novel mitogenomes of Hydropsychidae, of which the mitogenomes of the genus Arctopsyche are published for the first time. Coupled with published hydropsychid mitogenome, we analyzed the nucleotide composition evolutionary rates and gene rearrangements of the mitogenomes among subfamilies. As a result, we found two novel gene rearrangement patterns within Hydropsychidae, including rearrangement of protein-coding genes. Meanwhile, our results consider that the protein-coding gene arrangement of Potamyia can be interpreted by the tandem duplication/random loss (TDRL) model. In addition, the phylogenetic relationships within Hydropsychidae constructed by two strategies (Bayesian inference and maximum likelihood) strongly support the monophyly of Arctopscychinae, Diplectroninae, Hydropsychinae, and Macronematinae. Our study provides new insights into the mechanisms and patterns of mitogenome rearrangements in Hydropsychidae."

Abstract: "River regulation in the headwaters and middle reaches of the Gunnison River, Colorado, significantly altered distributions and abundances of Trichoptera fauna. Twenty-five species were collected from mainstream samples, with the greatest species richness occurring at an unregulated, rhithron segment above the central reach dams. At sites immediately below the three hypolimnial-release dams and a reregulation dam, species richness was reduced 35-90 per cent and abundance > 95 per cent. Net-spinning caddisflies were the dominant trichopterans at unregulated sites; Arctopsyche grandis in the upper reaches (218 organisms, 586 mg dry mass m-2) and Hydropsyche cockerelli, H. occidentalis and Cheumatopsyche pettiti in the lower river (9041 total organisms, 6621 mg m-2), downstream from the last dam. The observed distributional pattern of low trichopteran densities in dam tailwaters and high hydropsychid densities at sites 60-80 km below the central reach dams is a classic expression of continuum resets and adjustments in response to stream regulation as predicted by the Serial Discontinuity Concept.

Aquatic Sciences, 71(1), pp.3-14. PDF
Abstract: "We analysed the sensitivity of European Trichoptera (caddisfly) species to climate change impacts based on their distribution and ecological preferences, and compared the fraction of species potentially endangered by climate change between the European ecoregions. The study covers 23 European ecoregions as defined by Illies (1978). For 1134 Trichoptera species and subspecies, we coded 29 parameters describing biological and ecological preferences and distribution based on the evaluation of more than 1400 literature references. Five parameters served to describe the species’ sensitivity to climate change impacts: endemism, preference for springs, preference for cold water temperatures, short emergence period, and restricted ecological niches in terms of feeding types. Of the European Trichoptera species and subspecies, 47.9% are endemic, 23.1% have a strong preference for springs, 21.9% are cold stenothermic, 35.5% have a short emergence period, and 43.7% are feeding type specialists. The fraction of endemic species meeting at least one of the four other sensitivity criteria mentioned above is highest in the Iberic-Macaronesian Region (30.2% of all species), about 20% in several other south European ecoregions, and about 10% in high mountain ranges. In 15 out of 23 ecoregions (including all northern European and lowland ecoregions) the proportion is less than 3%.
The high fraction of potentially endangered species in southern Europe is a result of speciation during the Pleistocene. Species having colonised northern Europe afterwards have generally a large geographical range and are mainly generalists and thus buffered against climate change impacts."

Hinchliffe,R and Palmer,AR 2010 Curious chiral cases of caddisfly larvae: handed behavior, asymmetric forms, evolutionary history. Integrative and comparative biology, 50(4) 606-618. HTML
Abstract: "Studies of right-left asymmetries have yielded valuable insights into the mechanisms of both development and evolution. Larvae from several groups of caddisflies (Trichoptera) build portable asymmetrical cases within which they live. In nearly all species that build spiral-walled tubular cases, the direction of wall coiling is random (equal numbers of dextral and sinistral cases within species) whereas in all species that build helicospiral, snail-like cases the direction of coiling is exclusively dextral. Asymmetrical tubes result from handed behavior, and ~20% of larvae removed from a spiral-walled, tubular case build a replacement case of opposite chirality. So handed behavior (and hence direction of tube-wall spiraling) is likely learned rather than determined genetically. Asymmetrical larval cases appear to have evolved at least seven times in the Trichoptera, five times as spiral-walled tubes and twice as snail-like helicospiral cases. Helicospiral cases may reduce vulnerability to predation by mimicking snail shells, whereas spiral arrangements of vegetation fragments in tube walls may be more robust mechanically than other arrangements, but experimental evidence is lacking. Within one family (Phryganeidae), one or perhaps two species exhibit an excess of sinistral-walled cases, suggesting that genes that bias handed behavior in a particular direction evolved after handed behaviors already existed (genetic assimilation)."
Holzenthal,RW; Blahnik,RJ; Prather,AL and Kjer,KM 2007 Order Trichoptera Kirby, 1813 (Insecta), Caddisflies. Zootaxa, 1668: 639-698. PDF
Abstract: " The taxonomy, diversity, and distribution of the aquatic insect order Trichoptera, caddisflies, are reviewed. The order is among the most important and diverse of all aquatic taxa. Larvae are vital participants in aquatic food webs and their presence and relative abundance are used in the biological assessment and monitoring of water quality. The species described by Linnaeus are listed. The morphology of all life history stages (adults, larvae, and pupae) is diagnosed and major features of the anatomy are illustrated. Major components of life history and biology are summarized. A discussion of phylogenetic studies within the order is presented, including higher classification of the suborders and superfamilies, based on recent literature. Synopses of each of 45 families are presented, including the taxonomic history of the family, a list of all known genera in each family, their general distribution and relative species diversity, and a short overview of family-level biological features. The order contains 600 genera, and approximately 13,000 species"

Jannot,JE; Kerans,BL 2003 Body size, sexual size dimorphism, and Rensch's rule in adult Hydropsychid caddisflies (Trichoptera: Hydropsychidae). Canadian Journal of Zoology 81, 1956-1964.
Rensch's rule applies to a group of taxa, such as genera in a family or species in a genus. Rensch's rule states that sexual size dimorphism (SSD) decreases as the genus gets larger. Dimorphism means literally 2 (di) shapes (morphs) or in this instance, the difference in size between males and females. In most insects including caddisflies, females are usually bigger. Humans are sexually dimorphic too, except males are larger instead. So it turns out this study is interesting because Hydropsychids violate Rensch's rule. As the females get bigger, male size does not converge with female size. They focused on differences between genera, so it is possible Rensch's rule may apply at the species level. They suggest this result is due to average Hydropsychidae life history. Since the most selection pressure is on larvae, sexual selection (which affects male size) and fecundity selection (affecting female size) is not as strong in these species. It is also possible phylogenetic inertia is affecting SSD in Hydropsychids. Phylogenetic inertia is when selection on ancestral species created a pattern that hasn't changed in todays taxa yet even if the current selection pressures are different.

Abstract: " The occurrence and movement patterns of adult insects along a forested springbrook near Flathead Lake, Montana, USA, were studied during three 15-day periods from 19 June through 9 August 1985, using a two-sided Malaise trap. Of the Plecoptera, numbers of males and gravid females of Malenka flexura gravid females of Zapada frigida and total numbers of Paraperla wilsoni were significantly higher for downstream-flying adults during one to three periods. Of the Trichoptera, numbers of males of Anagepetus debilis were significantly higher for upstream flying adults during one period, and males of Lepidostoma cascadense and gravid females of L. spicata were significantly higher for downstream-flying adults during another period. In none of the 26 species examined in these three orders did females show a statistically significant pattern of upstream flight."

Abstract: "The effects of total organic carbon (TOC) and UV-B radiation on Zn toxicity and bioaccumulation in a Rocky Mountain stream community were assessed in a 10-d microcosm experiment. We predicted that TOC would mitigate Zn toxicity and that the combined effects of Zn and UV-B would be greater than Zn alone. However, TOC did not mitigate Zn toxicity in this study. In fact, treatments with TOC plus Zn had significantly lower community respiration as compared with the controls and Zn concentrations associated with the periphyton increased in the presence of TOC. UV-B had no additive effect on periphyton Zn accumulation or community respiration. Heptageniid mayflies (Ephemeroptera) were particularly sensitive to Zn, and reduced abundances were observed in all Zn treatments. UV-B did not additionally impact Heptageniid abundances; however UV-B did have a greater effect on macroinvertebrate drift than Zn alone. Ephemeroptera, Plecoptera, and Trichoptera (groups typically classified as sensitive to disturbance) were found in highest numbers in the drift of UV-B + Zn treatments. Measures of Zn accumulation in the caddisfly Arctopsyche grandis, periphyton biomass, and total macroinvertebrate abundance were not sufficiently sensitive to differentiate effects of TOC, UV-B, and Zn. These results indicate that UV-B and TOC affect Zn bioavailability and toxicity by impacting species abundance, behavior, and ecosystem processes. "

The Reverend William Kirby is considered a father of entomology. He studied insects in England in the late 1700's and early 1800's. Here are some quotes from this paper; " When we consider the vast number of non-descript species, with which, since Linné gave the last finish to his System of Entomology, the European cabinets of insects have been inundated, it seems remarkable that few or none have hitherto been discovered which will not arrange under some one or another of his orders:" and in a footnote he names the order Trichoptera. " If these remarks appear to entomologists well founded, and it be thought right to consider Phryganea as constituting a new order, I think it might be distinguished, since the wings of all the known species are hairy, by the name of Trichoptera.

Kjer,KM; Thomas,JA; Zhou,X; Frandsen,PB; Prendini,E and Holzenthal,RW; 2016 Progress on the phylogeny of caddisflies (Trichoptera). PDF
Abstract: "We present our current phylogenetic hypothesis on the phylogeny of Trichoptera, generated from an analysis of over 7000 nucleotides from 18S and 28S rRNA, EF-1α, COI, and CAD. We corroborate our earlier hypotheses, with results that include a monophyletic Annulipalpia, Integripalpia, Brevitentoria, and Plenitentoria. Monophyly of Psychomyioidea, Pseudoneureclipsidae, and Grumichellinae were confirmed. The "Spicipalpian" families were again found to be paraphyletic, and most closely related to Integripalpia. Ptilocolepidae was not found to be monophyletic, but support for its paraphyly was so weak that we interpret our results as unresolved. We interpret our measures of branch support, and present a collapsed phylogeny that more conservatively represents our current hypothesis. We discuss how these data can eventually be merged into other sources of data, such as COI barcode data and transcriptomes, and suggest that a single huge analysis of all data, with all taxa, is unnecessary if analyses can be phylogenetically subdivided into many separate parts, using transcriptome data to fix the deepest nodes, and allowing faster evolving data to be more appropriately targeted to nodes closer to the tips of the tree."

Abstract: "The phylogeny of Rhyacophilidae was explored with 28S ribosomal RNA (rRNA) and Cytochrome Oxidase Subunit I (COI) mitochondrial DNA (mtDNA). Eighty one rhyacophilids were included in the analysis. We found that although Rhyacophilidae was recovered as monophyletic, intrafamilial relationships are not well-resolved using this dataset. Bootstrap support was poor for intrageneric relationships and additional data will be required to present a more robust hypothesis. The recovered phylogeny places Fansipangana as the sister taxon of the rest of Rhyacophilidae. We found that Himalopsyche was nested inside the genus Rhyacophila with the verrula group sister to Himalopsyche and remaining Rhyacophila. These results and possible relationships should be tested with a more extensive data set."

Mihuc,TB and Mihuc,JR 1995 Trophic ecology of five shredders in a Rocky Mountain stream. Journal of Freshwater Ecology 10 (3) 209-216.
Abstract: "The trophic ecology of five shredder taxa found in Mink Creek, Idaho was determined in laboratory food quality experiments to assess the obligate or facultative nature of resource utilization among lotic taxa commonly referred to as detritivores. The experiments tested resource assimilation for each taxon among three major resources available to primary consumers in streams; periphyton, fine particulate detrital material (FPM) and coarse particulate detrital material (CPM). Growth of each taxon was determined on each resource in laboratory experiments conducted at 10 degree C. Growth results indicate that only one of the five taxa (middle-late instar Dicosmoecus atripes) was an obligate CPM detritivore. The remaining four taxa (Amphinemura banksi, Lepidostoma sp., Podmosta delicatula, and Zapada cinctipes) were generalists capable of growth on at least two of the three resource types. All four generalists exhibited growth on periphyton and CPM resources suggesting that these taxa can utilize both autochthonous and allochthonous resources. Our results do not support the idea that taxa with similar mouthpart morphology, specifically shredders, exhibit similar trophic relationships. "

Abstract: "Adult caddisflies of 138 montane and alpine lentic habitats, primarily lakes, of 7 northern Colorado counties are reported for the first time. Our objective was to provide species records of adult caddisflies from high-altitude lentic habitats that may potentially be impacted by current and future global climate change. Field collections of adults and captive rearing of larval specimens were coupled with unpublished records and an extensive review of published records, resulting in 541 confirmed caddisfly species records. Forty-nine caddisfly species, representing 24% of all known Colorado species are documented. Seven families and 21 genera are represented. The Limnephilidae comprised 76% of the 49 recorded species. The other 6 families were represented by only 1–4 species. One species was documented from alpine lakes only, 25 species from both montane and alpine lakes, 22 species from montane lakes only, and 1 species record could not be attributed to an elevation zone. We documented 6 regionally endemic species, 2 of which were recognized as vulnerable to extinction. Montane and alpine lakes are vulnerable ecosystems likely to be impacted by climate change. Comprehensive faunal surveys are key to understanding long-term biodiversity changes and establishing conservation needs and priorities. Species lists of taxa are important to monitor future faunal biodiversity changes."

Abstract: "The vitality of the phylogenetic dialogue in trichopterology, especially since 1967, is evidenced by the high quality and large number of published phylogenetic inferences concerning caddisflies and the continuing spirited exchange of opinions about some differences among those ideas. Monophyly for Trichoptera seems well argued. Monophyly for suborder Annulipalpia sensu stricto also is widely acknowledged, as is monophyly for suborder Integripalpia sensu stricto. Various postulated relationships of Hydrobiosidae, Rhyacophilidae, Glossosomatidae, and Hydroptilidae (= "Spicipalpia") are less convincing. Phylogenies for several groups of families within Annulipalpia and Integripalpia have been proposed and relationships within at least 126 infrafamilial taxa also have been inferred."

Abstract: "The holometabolous insect order Trichoptera (caddisflies) includes more known species than all of the other primarily aquatic orders of insects combined. They are distributed unevenly; with the greatest number and density occurring in the Oriental Biogeographic Region and the smallest in the East Palearctic. Ecosystem services provided by Trichoptera are also very diverse and include their essential roles in food webs, in biological monitoring of water quality, as food for fish and other predators (many of which are of human concern), and as engineers that stabilize gravel bed sediment. They are especially important in capturing and using a wide variety of nutrients in many forms, transforming them for use by other organisms in freshwaters and surrounding riparian areas. The general pattern of evolution for trichopteran families is becoming clearer as more genes from more taxa are sequenced and as morphological characters are becoming understood in greater detail. This increasingly credible phylogeny provides a foundation for interpreting and hypothesizing the functional traits of this diverse order of freshwater organisms and for understanding the richness of the ecological services corresponding with those traits. Our research also is gaining insight into the timing of evolutionary diversification in the order. Correlations for the use of angiosperm plant material as food and case construction material by the earliest ancestors of infraorder Plenitentoria-by at least 175 Ma—may provide insight into the timing of the origin of angiosperms."

Abstract: " In stream-living Potamophylax cingulatus, current velocity was found to be an ultimate factor in guiding settlement of the larvae prior to pupation, areas of high current velocity being avoided. In areas suitable for pupation, i.e. in a low current regime, the larvae formed aggregations only under certain stones. Most pupae were found in large (> 40 inds.) aggregations, where also hatching success was highest. Infestation by a chironomid larva, Polypedilum fallax Joh., peaked at intermediate aggregation size. We suggest pupal aggregations to be formed in order to reduce the risk of becoming a victim of the chironomid. "

Toxics, 9(10), p.256. PDF
Abstract: "Microplastics (MPs) pose biological and chemical hazards in aquatic and terrestrial food webs across the globe. Research on microplastic contamination has long focused on marine ecosystems, whereas the toxicological impact on freshwater organisms is still little explored. In this study, the lethal and sublethal response of the freshwater macroinvertebrate Hydropsyche pellucidula exposed to polypropylene MPs after different pre-conditioning treatments was assessed. Field samples were collected in a riverine system (Vipacco river; northeast Italy) to assess the characteristics of the MPs in the aquatic environment Both water and sediment were contaminated by MPs (3.73 ± 2.11 items m-3 per min and 3.33 ± 4.16 items dm-3, respectively). The chemical MPs composition included polystyrene, polyethylene terephthalate, polyurethane, polyamide, polypropylene, and polyethylene. Polypropylene (PP), although not the most abundant polymer recorded in the study area, was preferred over the other types according to its abundance in freshwater and H. pellucidula feeding behavior. A housing test was performed to recreate the natural conditions of larvae sampled for a reliable response to the ecotoxicological tests. The microplastics underwent either preconditioning with Vipacco River water (PP-river) and surfactant Triton X-100 (PP-sf) or no pre-treatment (PP). Submersion of microplastics in 10 µg L-1 of surfactant solution for 24 h was sufficient to induce consistent spectral changes and modify the chemical profile of the plastic surface. Mortality rate differed according to treatment: PP and PP-river > positive control > PP-sf > negative control. Integrated biomarker response (IBRv2) and analysis of oxidative stress biomarker levels showed a greater response of superoxide dismutase and lipid peroxidation (malondialdehyde) in larvae treated with PP conditioned in surfactant. Our findings enhance knowledge on the toxicity of PP and conditioning phases on H. pellucidula larvae."

Larvae were supplied various food sources (bacteria, algae, and invertebrates) and case building materials. This technique permits casemaking and other aspects of larval behavior to be observed, and allows for complete description of associated larvae. "

After compositing 3 surber samplers in the field, back at the lab they identified the macroinvertebrates to genus level and used a diversity index to evaluate the health of the macroinvertebrate community. Higher diversity is better. Diversity decreased downstream of heavy metal pollution from the Leadville Drain and California Gulch and increased downstream of clean water inputs.

Abstract: "The Trichoptera, or caddisflies, are traditionally split into two taxonomic subdivisions: the ‘retreat-making’ Annulipalpia and the ‘case-making’ Integripalpia (sensu Ross). The monophyly of these groups is well documented; however, the establishment of a third subdivision, ‘Spicipalpia’, and the positions of the five ‘spicipalpian’ families is much debated. In contrast to previous molecular studies using nuclear ribosomal RNA, a recent trichopteran study (using nuclear protein-coding genes) placed one of these ‘spicipalpian’ families, the free-living predatory Rhyacophilidae, as the sister taxon to the rest of Trichoptera, a result that has significant implications for both the understanding of trichopteran evolution and its timing. This paper sets out to investigate the relationships of Trichoptera using several newly sequenced genes, together with previously published gene sequences. This dataset is the largest trichopteran dataset to date, covering six independent genes and > 10 000 nucleotides, and containing 185 species representing 49 families. With all data included, likelihood and Bayesian analyses support a monophyletic Annulipalpia and a monophyletic Integripalpia, which includes the ‘spicipalpians’ as a paraphyletic grade at the base of this clade. However, an analysis of the protein-coding data alone using similar analytical methods recovers Rhyacophilidae as the most basal taxon in Trichoptera, with low support. A reanalysis correcting for nucleotide composition bias provides support for the placement of the ‘spicipalpian’ taxa as sister to the Integripalpia, consistent with the total data analysis, suggesting that the basal position of Rhyacophilidae in the uncorrected analysis could be (or is probably) an artefact of base composition. We find it likely that ancestral trichopterans made incipient cases and retreats, and these had independent origins as precocious pupal chambers. Molecular dating analysis in beast, using the birth-death model of speciation, with a relaxed-clock model of sequence evolution informed by 37 fossil constraints, suggests that the most recent common ancestor of Trichoptera appeared in the Permian (c. 275 Ma) in line with the first appearance of Trichoptera in the fossil record, and that vicariance explains the distribution of most trichopteran taxa. A new infraordinal name, Phryganides, is introduced for the tube-case-making families of Integripalpia."

Abstract: "A phylogeny of the families of Trichoptera is reviewed to provide a basis for understanding the probable evolution of feeding tactics and case or retreat constructions by larvae. At least 48 hierarchically inclusive homologues are known, mostly from larval, pupal, and adult morphology. Their resulting phylogeny indicates that Rhyacophilidae, Hydrobiosidae, Glossosomatidae, and Hydroptilidae are more closely related to Philopotamidae, Hydropsychidae, and their allies than to Limnephilidae, Leptoceridae, and their allies. This phylogeny implies that the ancestral caddisfly larva was probably a tube-dwelling detritivore, inhabiting humus and detrital mats near the shores of lentic or lotic-depositional habitats. This ancestor evolved into a tube-case-making detritivore and scraper in the ancestor of Integripalpia and into a retreat-making collector-gatherer in the ancestor of Annulipalpia. All other larval feeding and case-making tactics evolved from these ancestral habits."

Wichard,W 2021 Overview of the caddisflies (Insecta, Trichoptera) in mid-Cretaceous Burmese amber. Cretaceous Research, 119, p.104707.
Abstract: "The study of caddisflies in mid-Cretaceous Burmese amber is still in its infancy, it being too early to get more than a preliminary overview of the Trichoptera fauna. With description here of two new and significant taxa, Cretacoptila botosaneanui gen. et sp. nov. and Electrocentropus dilucidus gen. et sp. nov. a total of 34 named species are listed, distributed among 10 families. Several taxonomic changes are made: two established species are transferred to more-appropriate genera, becoming Neucentropus macularis (Wang et al., 2019) comb. nov. and Myanpsyche malaisei (Wichard & Wang, 2019) comb. nov.; a new extinct subfamily † Burminoptilinae subfamily nov. is proposed in the family Hydroptilidae and two extinct families, † Burmapsychidae fam. nov. and † Cretapsychidae fam. nov., are proposed for the superfamily Sericostomatoidea.
The small size of adults of many of these species is remarkable. With their 2–4 mm length forewings they are smaller than their next relatives in the Baltic Amber and even much smaller than their present representatives. Thus, not only are the hydroptilids “microcaddisflies”, but also philopotamids of the genus Wormaldia and psychomyiids of the extinct genus Palerasnitsynus, which, being the most common caddisflies in Burmese amber, apparently tended to swarm."

This is the bible for Caddisfly identification in North America. This book has excellent illustrations and keys. Each genus has a short discussion of Distribution and Species, Morphology, Case, Biology and Remarks. The illustrations and bibliography are worth the cost of the book alone. As of the publication of this book, Wiggins says we have 149 genera of caddisflies in North America and he has keys to the larvae of all of them except for 4 where the larvae have not been associated.

Abstract:"Two hypotheses exist as to the function of the tubular cases constructed from silk and debris by caddisfly (Trichoptera) larvae. One proposes that they provide protection for the larvae by camouflaging them against their background or by providing resistance to the jaws of predators. The other proposes that the case acts as an aid to respiration as, by undulating its abdomen, the larva can create a flow of water through the case and over its gills. We measured, in respirometer chambers at 13°C, the uptake of dissolved oxygen by larvae of 22 species of caddisfly representing a variety of habitat types and phylogenetic lines. Oxygen uptake by larvae in their cases was compared with that of larvae without cases and the species fell into three basic groups: in Group A, representing seven families, the cases appeared to confer a respiratory advantage upon the larvae through reduced levels of oxygen uptake and moderation of respiration rates (i.e., by optimizing rather than maximizing oxygen consumption); in Group B, representing two families, the cases appeared to be a disadvantage to respiration (larvae in their cases consumed more oxygen than they did in the absence of their cases); and in Group C, representing the largest family, the Limnephilidae, for most of the species tested the cases appeared to confer no respiratory advantage (no differences between the amounts of oxygen consumed by larvae in their cases and alone). Given the many uses to which silk has been put in the Trichoptera, it seems reasonable to suppose that construction of a tubular case does not dictate a single function across all case-building species. Our data point to a respiratory function in some species but to a non-respiratory function (probably protection from predators) in others, particularly in the Limnephilidae."

Abstract: "Few in situ studies have investigated the biological drivers of detritus processing in shallow lentic systems, despite abundant evidence that vascular plant detritus is a primary source of nutrients and energy. In particular, the relative importance of microbial decomposers and animal detritivores to overall detritus breakdown is poorly documented. Caddisfly larvae (Trichoptera: Limnephilidae) are often the biomass-dominant animal detritivores in high-elevation and high-latitude ponds and wetlands in the northern hemisphere. The larvae of many limnephilid caddisfly species are shredders that rely on detritus as their primary food source, and they may therefore play an important role in litter breakdown in lentic systems. Here, we manipulated abundances (present/absent) of caddisfly larvae in shallow montane ponds in Colorado, and compared sedge detritus breakdown rates across treatments. We found that coarse particulate organic matter (CPOM) was converted to fine particulate organic matter (FPOM) 2 to 3× faster when caddisflies were allowed access to the detritus than when not, indicating that caddisflies play a key role in litter breakdown in these temporary habitats. Dietary data from the 6 species of caddisflies in the ponds revealed that all primarily consume CPOM derived from vascular plants, although the ratios of CPOM and FPOM in the diets varied among species. The biomass of caddisflies relative to detrital inputs is particularly high at our study sites compared with other eutrophic, low-elevation wetlands. Thus, we suspect that animal detritivory relative to microbial processing may be especially high in these ponds. Future in situ, whole-community studies in basins that differ in hydroperiod, nutrient status, and ratio of detrital inputs to detritivore biomass will be needed to construct a general model of detritus breakdown in shallow lentic freshwater habitats."
