Abstract: "The epiproct complex and other details of the male terminalia of the Holarctic stonefly subfamily Brachypterainae are illustrated by scanning electron microscope micrographs or images. Selected species of eight of the 12 genera, Bolotoperla, Doddsia, Oemopteryx, Strophopteryx, Taenionema, Mesyatsia, Brachyptera, and Rhabdiopteryx are examined. Three images are provided for each species, which usually include a dorsal view of the male terminalia and close up views of the epiproct complex or other genital structures. These genera are organised in a zoogeographical format beginning with the Nearctic fauna and subsequently moving in a westerly direction around the globe, ending with the west Palearctic fauna. Locality data are given for all specimens illustrated. "

Canton,SP and Ward,JV 1981 The aquatic insects, with emphasis on Trichoptera, of a Colorado stream affected by coal strip-mine drainage. Southwestern Naturalist 25 4, 453-460.
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 in riparian vegetation 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.
Prostoia besametsa was most common at the clean, forested, shaded, upstream site. It was probably more common here partly because it is a shredder and needs leaves to eat.

Clubb,RW; Gaufin,AR and Lords,JL 1974 Acute cadmium toxicity studies upon nine species of aquatic insects. Environmental Research 9(3) 332-341.
Abstract: Continuous-flow bioassays were employed to determine 96-hour median tolerance limits (TLm), for the stonefly, Pteronarcella badia (Hagen) (TLm was 18.0 mg Cd/l) and the mayfly, Ephemerella grandis grandis Eaton (TLm was 28.0 mg Cd/l). Ninety-six hours TLm values for other species of aquatic insects tested were not determined, since these species were relatively insensitive to cadmium.
Insects exposed for four days in cadmium-containing water, then placed in tap water, show a linear rate of cadmium loss. This loss may lower or prevent mortality under ideal conditions.

Abstract: The summer emergence patterns of mayfly, stonefly, and caddisfly species are described for a second order, southern Rocky Mountain Colorado stream. Frequent, standardized, sweepnetting and emergence trap samples provided 1,779 adults of 45 taxa consisting of 11 mayfly, 15 stonefly, and 19 caddisfly species. The five most dominant species were, in order of importance, Suwallia nr. lineosa, Sweltsa coloradensis, Oligophlebodes minutus, Paraleuctra vershina, and Baetis bicaudatus. Stoneflies contributed 70% of all adults collected. Peak species richness of all orders occurred near the summer solstice and maximum water temperatures. The range of slope values generated by simple linear regression of cumulative percentage catch revealed that emergence was extended (slopes < 4%/day) for five of the seven most abundant species. Two caddisflies, O. minutus and Rhyacophila pellisa, displayed a synchronous emergence pattern. This study adds 35 new records for the Rio Conejos drainage and Conejos County and provides a baseline of comparison against future changes in species richness among these orders.

Abstract: "The stonefly component of a naturally reproducing population of brook trout (Salvelinus fontinalis) was studied by analyzing 216 stomach pump samples collected between May 15 and August 10, 1991 and 1992, from Libby Creek, an alpine stream in the Medicine Bow National Forest in Wyoming. Stoneflies constituted 10.3% of the total items recovered and were the second most abundant order in the samples. Nineteen species of Plecoptera representing five families were identified. Approximately 43% of all stoneflies were Sweltsa lamba; the next most prevalent species was Zapada haysi (12%). The other prevalent insect orders in the samples were Diptera (57.2%), Ephemeroptera (8.4%) and Trichoptera (6.1%). Terrestrial Coleoptera, Hymenoptera, and Hemiptera were most common in July and August."

Abstract: Plecoptera, or stoneflies, is a small order of hemimetabolous insects: according to our data, more than 3,497 species have been described so far in the world. The total number of species has enormously increased in the last 30 years (2,000 species estimated in 1976) and, if the trend continues, then it will nearly double in the near future. The order is divided into the suborders Arctoperlaria and Antarctoperlaria, and includes 16 families: 12 arctoperlarian and 4 antarctoperlarian. The Arctoperlaria
account for a total number of 3,179 species, and Antarctoperlaria, only 318 species. The total number of genera is 286. We give in this article the estimated number of species for each family. The fauna and diversity of stonefly in North America (650 species reported) and Europe (426 species) are best known. Nevertheless, in the last 25 years, a mean of 2.6 Plecoptera species per year were described in Europe. Stonefly-faunas of Australia (191 species, Tasmania included) and New Zealand (104 species) are relatively well-known, while our knowledge of the Plecoptera of Central and South America (95 and 378 species respectively) is poor and still not representative of the real diversity. Africa has a reduced stonefly fauna (126 species). Asian stonefly diversity (approximately 1,527 species) is much greater than that of Europe or North America despite the fact
that, except for Japan and Asiatic Russia that have been well studied, our knowledge of the remaining Asiatic areas is extremely poor. Even though our data indicate the Holarctic Region as the diversity hot-spot for the order, the analysis of the specific diversity divided by family suggests also an important role of tropical stoneflies.

Abstract: Gut contents of 1013 stonefly nymphs, comprising nine species, from the Dolores River, Colorado, were analyzed from December 1974 - October 1975 and compared with food availability. Pteryonarcyids ingested large quantities of detritus and some moss, moss being a substantial food item in later instar Pternarcella badia nymphs. Perlodids fed primarily on chironomids and simuliids, although Isoperla fulva also ingested mayflies in June. Claassenia sabulosa remained carnivorous throughout development: young nymphs ingested chironomids and small mayflies and larger nymphs ingested caddisflies and mayflies. Horn's Coefficient of Dietary Overlap indicated significant overlap between all perlodids and chloroperlids. It also showed significant overlap between small and large C. sabulosa nymphs, yet selection of different prey sizes indicated resource partitioning. A comparison of food habits with the Gunnison River stoneflies indicated differences between the diets of large and small Claassenia sabulosa, with chironomids comprising large percentages of the diet for both size classes in the Gunnison River and smaller nymphs in the Dolores. Mayflies were important prey for larger individuals in the Dolores River. These differences could be attributed to different prey populations in each river and/or to availability of prey in the particular size that each predator preferred. In both rivers, Chironomidae and Simuliidae larvae were the major prey in the guts of Cultus aestivalis and Isoperla fulva. This prey specificity may have been due to decreased availability of smaller individuals in the other major prey groups or a difficulty in capture of larger prey organisms.

Specifically, mayflies and some stoneflies were sensitive, and caddisflies and chironomids were relatively tolerant to metal exposure. However, the sensitivity to metals differed within families, genera and across lifestages."
Knight,AW; Gaufin,AR 1966 Altitudinal distribution of stoneflies (Plecoptera) in a Rocky Mountain drainage system. Journal of the Kansas Entomological Society 39 4, 668-675. First page
Abstract: "Stoneflies collected between the altitude of 6,760 and 10,770 feet in the Gunnison River drainage, Colorado, show definite altitudinal distribution. The effect of altitude on stonefly distribution is largely due to temperature and, in part, food supply. The greatest number of stonefly species was recorded between 7,000 and 9,000 feet. Carnivorous stonefly species were dominant at all elevations and reached high dominance values at the higher elevations."
Stonefly names have changed quite a bit since this publication.

Abstract: " lnsect wings appear to have evolved from gills used by aquatic forms for ventilation and swimming, yet the nature of intermediate stages remains a mystery. Here a form of nonflying aerodynamic locomotion used by aquatic insects is described, called surface skimming, in which thrust is provided by wing flapping while continuous contact with the water removes the need for total aerodynamic weight support. Stoneflies surface skim with wing areas and muscle power output severely reduced, which indicates that surface skimming could have been an effective form of locomotion for ancestral aquatic insects with small protowings and low muscle power output."

Abstract: " At the very tips of most drainage networks are small stream channels, many of which have no flow at times during the summer. These small, zero-order streams contribute a significant portion of cumulative stream length in a watershed, but are largely unexplored and receive little protection under current legislation. We studied the aquatic macroinvertebrate assemblage of 7 small coastal streams with a range of permanence of flow. Three streams have no detectable surface flow for periods in summer (i.e., intermittent flow). We hypothesize that the invertebrate assemblage in these zero-order streams does not completely overlap that of larger streams. Stream sites were sampled using a combination of emergence traps emptied every 14 days throughout the year. In even the smallest streams (<0.5 m bankfull width) with intermittent flow, true aquatic insects with 1-year life cycles were found emerging, even in periods when no flow was perceptible. Species richness in intermittent and continuous streams was approximately equal, while intermittent streams appeared to produce as much as twice the number of adult stoneflies as continuous streams. This study shows that even intermittent streams harbour a true aquatic fauna and, potentially, species for which little is known, and indicates that these unique habitats make an important contribution to their ecosystems."

Petrin,Z 2011 Species traits predict assembly of mayfly and stonefly communities along pH gradients. Oecologia, 167(2), 513-524. Abstract
Abstract: " Much recent ecological research has centred on the interrelations between species diversity and ecological processes. In the present study, I show how species traits may aid in comprehending ecology by studying the link between an environmental variable and functional traits. I examined the composition of species traits with a theoretically underpinned relationship to ecological processes along a pH gradient. I focused on body size, reproductive output, life cycle length and feeding habit of mayflies and stoneflies. In mayfly assemblages, I found smaller body size, greater reproductive output, faster life cycles and a larger proportion of gathering collectors and scrapers with increasing pH. In stonefly assemblages, I found smaller body size, greater reproductive output and faster life cycles at sites with a history of long-term natural acidification, but no clear trends in feeding habits and in most traits where acidification is anthropogenic. The results suggest that mayflies and stoneflies exhibit different ecological functions following different ecological strategies. Mayflies follow an opportunistic strategy relative to stoneflies, likely facilitating high rates of ecological processes with respect to the autotrophic resource base at neutral sites. Relative to mayflies, stoneflies follow an equilibrium strategy contributing to ecological functioning in heterotrophic ecosystems and likely maintaining heterotrophic processes despite the erosion of species diversity in response to acidification. The rules governing an ecological community may be more readily revealed by studying the distribution of species traits instead of species diversity; by studying traits, we are likely to improve our understanding of the workings of ecological communities.

After compositing 3 surber samplers in the field, they took the samples back to the lab and identified the macroinvertebrates to genus level. The author 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: Static bioassays were conducted to determine the relative acute toxicities of some insecticides, herbicides, fungicides, a defoliant, and a molluscicide to the naiads of three species of stonefly, Pteronarcys californica, Pteronarcella badia, and Claassenia sabulosa. Toxic effects were measured by determination of median lethal concetration (LC50) for 24-, 48-, and 96-hr exposures, at 15.5C. Endrin and dieldrin were the most and DDT the least toxic of the chlorinated hydrocarbon insecticides tested. Parathion was the most toxic organophosphate insecticide to P. californica naiads, but Dursban was the most toxic to P. badia and C. sabulosa naiads. Trichlorofon (Dipterex) was the least toxic to all three species. P. badia, the species of smallest size, was the species most susceptible to most pesticides, followed in descending order of sensitivity by C. sabulosa and P. californica. Smaller specimens of P. californica naiads were consistently more susceptible to some insecticides than larger specimens of the same species.

Reviews history of describing and naming gills on the stoneflies of North America. Standarizes the terminology of gills. Suggests since function of the things we call gills appears to really be for osmoregulation that we call most of the gills on stonefly nymphs osmobranchiae. The only truly respiratory gills on stoneflies are the gills variously referred to as anal, caudal (historic terms) or subanal lobe (SL) gills found on Perlidae and Pteronarcyidae nymphs. Perlid and Pteronarcid nymphs grow more gills and more branches on their gills with sucessive instars. Many other gilled stoneflies gain gills as they grow making identifications based on gills problematic for immature specimens.

Stanford,JA and Ward,JV 1993 An ecosystem perspective of alluvial rivers: connectivity and the hyporheic corridor. Journal of the North American Benthological Society, 48-60.
Abstract: " Floodplains of large alluvial rivers are often expansive and characterized by high volume hyporheic flow through lattice-like substrata, probably formed by glacial outwash or lateral migration of the river channel over long time periods. River water downwells into the floodplain at the upstream end; and, depending on bedrock geomorphology and other factors, groundwater from the unconfined aquifer upwells directly into the channel or into floodplain springbrooks at rates determined by head pressure of the water mass moving through the floodplain hydrologic system. These large scale (km3) hyporheic zones contain speciose food webs, including specialized insects with hypogean and epigean life history stages (amphibionts) and obligate groundwater species (stygobionts). Biogeochemical processes in the hyporheic zone may naturally load groundwaters with bioavailable solutes that appear to exert proximal controls on production and biodiversity of surface benthos and riparian vegetation. The effect is especially evident in floodplain springbrooks. Dynamic convergence of aquifer-riverine components adds physical heterogeneity and functional complexity to floodplain landscapes. Because reaches of aggraded alluvium and attendant ecotonal processes occur serially, like beads on a string, along the river continuum, we propose the concept of a hyporheic corridor in alluvial rivers. We expect predictable zonation of groundwater communities and other aquifer-riverine convergence properties within the corridor from headwaters to river mouth. The landscape-level significance and connectivity of processes along the hyporheic corridor must be better understood if river ecosystems, especially those involving large floodplain components, are to be protected and/or rehabilitated.

Abstract: " A long recognized but little explored mode of intersexual communication in insects is use of low-frequency substrate-borne vibrational signals. Representatives of 10 insect orders are known to have adopted this mode; range of communication, informational content and receiver integration of signals and energy costs are discussed. Arctoperlarian stoneflies represent the epitome of evolution of vibrational communication. Their ancestral signals were monophasic volleys of evenly spaced drumbeats. Derived signals to achieve species-specificity and possibly to enable sexual.selection or some measure of reproductive fitness has involved modification of the ancestral form toward complex signals through: (1) changes in the rhythmic patterning of calls, (2) patterns of ?-? duetting, and/or changes in the method of signal production such as rubbing or tremulation. Proposed paradigms for the evolution of vibrational communication and evolution of signal patterns are presented, with examples of the signals of several arctoperlarian species. The entire mating system of Arctoperlaria is discussed, and searching behavior in relation to vibrational communication is presented for Pteronarcella badia, Claassenia sabulosa, Perlinella drymo and Suwallia sp.

Abstract: Nymphal growth and emergence of adults are described for six species of stoneflies (Plecoptera) found in subarctic and arctic Alaska. The two Nemouridae studied are semivoltine; adults of Zapada haysi (Ricker) are present from May to July and adults of Nemoura arctica Esben-Petersen occur from June to July. The remaining four species are univoltine. Plumiperla diversa (Frison) (Chloroperlidae) has most of its growth occurring during the summer with emergence the following May-September. Taenionema pacificum (Banks) (Taeniopterygidae) completes nymphal growth by the end of January and has an early emergence (April-June). Adults of Arcynopteryx compacta (McLachlan) (Perlodidae) are present from May to August, and growth of nymphs is rapid during summer and fall. Isoperla petersoni Needham ∓ Christenson (Perlodidae) adults are present from June to mid-August, and nymphal growth is interrupted by winter and resumes in the spring; the three other univoltine species studied tend to complete growth before the onset of winter. Growth of these six species is tied to seasonal temperature variation.
Stewart,KW and Maketon,M 1991 Structures used by Nearctic stoneflies (Plecoptera) for drumming, and their relationship to behavioral pattern diversity. Aquatic insects, 13(1), 33-53.
Abstract: " There has been some co-evolution of male ventral abdominal structure with method of producing vibrational call signals and call pattern diversity in Plecoptera. Male Antarctoperlaria have no specialized ventral abdominal structures and are not known to drum. Male Arctoperlaria without vesicles, lobes, knobs or hammers all produce relatively simple calls by tapping on substrate, or have derived a tremulation method of producing calls. Elongate, moveable vesicles on abdominal segment 9 are homologous structures in ancestral and some extant Euholognatha families, and are primarily associated with ancestral call patterns. Allocapnia and Taeniopteryx, that have secondarily lost vesicles, have retained the ancestral drumming pattern. The lobes, knobs and hammers of Systellognatha, that are characterized with SEM in this paper, are probably non-homologous with vesicles of Euholognatha, and presumably have arisen independently in various families and genera. Systellognathan species with these structures have either retained ancestral, tapping call patterns, or have derived highly specialized grouped, or phased patterns or a rubbing method of signal production. Rubbing has been derived only in association with the knobs of Peltoperlidae or hammers of Perlidae. Complex drumming pattern diversity is unnecessary in females, and as expected, we have found no complex answer patterns, rubbing method of answering or specialized drumming structures in them. "

Studying Megarcys in streams around the Rocky Mountain Biological Lab in Gothic, Colorado, they found that M. signata was protandrous (males emerge first) and females were about twice the body mass of males in both streams studied. M. signata emerged earlier and larger from a trout stream (East River) than the stoneflies from a smaller fishless tributary (Benthette Brook). Temperature did not affect size at metamorphosis. Many females from Benthette Brook were brachypterous (short-winged), while East River Megarcys females has longer wings. In 1992 East River stoneflies emerged from mid June to mid July with the peak emergence in late June. Benthette brook Megarcys emerged from early July to late August, peaking in Late July. Adults emerged at dawn between 0600 and 0800 hours until later in the season when they emerged at night (after 2200 hours). Adults became more active after dark. Manipulative experiments determined that male body mass did not affect reproductive success. Sometimes male drumming attracted females who mated immediately upon finding the male. Other times the first male to stumble on the female mated with her. Mating usually occurred within the first three days after emergence. Copulation generally lasted all night. Females who mated multiple times had lower total lifetime fecundity than females who mated once. Multiple matings reduced the lifespan of males and females. There was no evidence of parthenogenesis in unmated females. Neither sex fed on sugar water except rarely and dissections of field collected adults showed atrophied digestive tracts.

Abstract: " Information about the phylogenetic relationships of Plecoptera is summarized. The few characters supporting monophyly of the order are outlined. Several characters of possible significance for the search for the closest relatives of the stoneflies are discussed, but the sister-group of the order remains unknown. Numerous characters supporting the presently recognized phylogenetic system of Plecoptera are presented, alternative classifications are discussed, and suggestions for future studies are made. Notes on zoogeography are appended. The order as such is old (Permian fossils), but phylogenetic relationships and global distribution patterns suggest that evolution of the extant suborders started with the breakup of Pangaea. There is evidence of extensive recent speciation in all parts of the world."

"One final paragraph of advice: Do not burn yourself out. Be as I am - a reluctant enthusiast... a part-time crusader, a half-hearted fanatic. Save the other half of yourselves and your lives for pleasure and adventure. It is not enough to fight for the land; it is even more important to enjoy it. While you can. While it is still there. So get out there and mess around with your friends, ramble out yonder and explore the forests, encounter the griz, climb the mountains. Run the rivers, breathe deep of that yet sweet and lucid air, sit quietly for a while and contemplate the precious stillness, that lovely, mysterious and awesome space. Enjoy yourselves, keep your brain in your head and your head firmly attached to your body, the body active and alive, and I promise you this much: I promise you this one sweet victory over our enemies, over those deskbound people with their hearts in a safe deposit box and their eyes hypnotized by desk calculators. I promise you this: you will outlive the bastards." -- Edward Abbey
