Stoneflies - Plecoptera: Pteronarcyidae of Gunnison County, Colorado
Pteronarcella badia Least Salmonfly(Hagen) 1874
Updated 25 Feb 2016
HabitatSlow areas of streams and rivers in debris such as leaf packs.
Life HistoryP. badia has one generation per year (univoltine) with peak emergence in late June in the Gunnison River at Lost Canyon Resort (Fuller and Stewart 1977). Fuller and Stewart noted P. badia had a diet high in detritus, with large quantities of moss in the winter and spring months. Small nymphs appeared in September and fed primarily on detritus. The desmid Cosmarium was abundant in the river and guts in September and October. Diatoms were 11 and 15% of nymphs diet in September and October respectively. It appears P. badia uses conditioned fall leaf debris in the fall thru winter and eats more mosses right before emergence. Richardson and Gaufin 1971 noted this species is primarily herbivorous. P. badia ate higher plant and mosses in the Lake Fork of the Gunnison. Diatoms were also found in the guts. Specimens collected in the spring ate mostly Ephemeroptera and Plecoptera, some ate Chironomids. They change diets when plant material is unavailable. P. badia distributions overlap with Pteronarcys californica and their diets are similar, however P. californica is more omnivorous.
Locations CollectedLake Fork of the Gunnison, Gunnison River at the Lost Canyon Resort, Cement Creek, Agate Creek, Sapinero Creek
NotesOlder publications may refer to this species as Pteronarcys badia.

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.

While describing a new species of fossil Pteronarcyidae that pushes the origin of the family to the Jurassic (165 million years ago), they also publish photos of Pternarcella badia wings after noticing a lack of such information in the current literature.
Quote: "Wing venation variability in Pteronarcella badia During our survey, we discovered that there was a lack of data on the wing venation of Pteronarcella badia, a critical species for comparison. An incomplete view of a forewing is available in Needham & Claassen (1925)  (Fig. 11), and a fore- and a hind wing are illustrated by Nelson & Hanson 1971 : (Figs. 23-26). We investigated nine macropterous specimens (three males, six females). The typical morphology of the species is represented by Fig. 1a-d for males and Fig. 1e-h for females. In both fore- and hind wing, it involves a 3- or 4-branched RP, a 2-branched M (i.e. both MA and MP simple), a simple CuA, and no cross-veins in the area between R/RP and M basal to the first fork of M. In forewings, the rp-ma cross-vein is long, and AA2 has 2-3 branches."

Abstract: " Gut contents of 1,463 stonefly nymphs, comprising 10 species, from the Gunnison River, Colorado, were analyzed from Dec., 1974-Oct., 1975, in relation to food availability. Pteronarcella badia fed primarily on detritus and moss. Perlidae and Perlodidae mature nymphs were all carnivorous, but showed considerable seasonal-developmental shifting in diets and preference during earlier stages. Early instar Isoperla fulva nymphs were herbivore-detritivores, then gradually shifted through an omnivorous to carnivorous diet as development proceeded. Claassenia sabulosa and Hesperoperla pacifica remained carnivorous throughout development. Dominant prey groups were chironomids, mayflies and caddisflies. Horn's Coefficient of Dietary Overlap showed significance among all predator species for major food categories, but subtle mechanisms such as prey species-and size-selectivity and temporal succession provided sufficient partitioning of the abundant food resources to allow for coexistence. Large Claassenia sabulosa nymphs in August selected more mayflies after dark than in the afternoon. No behavioral selection by predacious stoneflies was indicated for the chironomids Ablabesmyia sp., Cricotopus sp., Prodiamesa sp., and Rheotanytarsus sp. "
Fuller,RL and Stewart,KW 1979 Stonefly (Plecoptera) Food habits and prey preference in the Dolores River, Colorado. American Midland Naturalist, 101(1) 170-181. First page
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."

Abstract: "The mature larvae of fifteen species of aquatic insects (Diptera, Ephemeroptera, Plecoptera, and Trichoptera) and the scud (Amphipoda) were tested to determine their relative sensitivity to heated waters under laboratory conditions. The temperature at which 50% died after 96 hours (TLm96) was recorded as the lethal temperature. This ranged from 11.7 C for the torrential stream mayfly, Cinygmula par Baton, to 32.6 C for the snipefly, Atherix variegata Walker. " The TLm96 for P. badia was 24.4°C.

Abstract: " Claassenia sabulosa (Banks) and Pteronarcella badia (Hagen) stonefly nymphs were examined for distributional responses in an experimental setting. In treatments with single individuals and groups of four, P. badia, a shredder, distributed itself in proportion to the available surface area among fibrous, non-food substrates of different sizes. In treatments with four and fourteen P. badia, the nymphs demonstrated aggregation, often with body contact. Its distribution became random and significantly different from substrate surface area in the presence of C. sabulosa, a predator, indicating an interspecific interaction."

Quote from page 1512: "Variation among taxa: Metal concentrations in organisms collected from station AR-5 [impacted by heavy metal pollution from California Gulch] (fall, spring, summer) varied significantly among taxa (Fig 7). The highest concentrations were generally found in the mayfly Baetis spp., the stonefly Pteronarcella badia, and the caddisfly Arctopsyche grandis, whereas the lowest levels were measured in the two predators, Skwala americana, and Rhyacophila spp."
Kiffney,PM; Clements,WH 1996 Size-dependent response of macroinvertebrates to metals in experimental streams. Environmental Toxicology and Chemistry 15(8)1352-1356.
Abstract: "Our previous research has shown that the effects of metals on stream benthic invertebrate populations and communities can vary within and between locations. With this in mind, we examined whether invertebrate body size could explain some of the variation in metal sensitivity within a species. Benthic macroinvertebrates from a pristine Rocky Mountain foothills' stream were collected using artificial substrates and exposed to a mixture of Cd, Cu, and Zn in stream microcosms for 10 d at their respective Colorado chronic criterion levels (4.0, 5.0, and 50 mu g/L). The effects of metals on the ephemeropterans Baetis tricaudatus (Baetidae), Ephemerella infrequens (Ephemerellidae), and Rhithrogena hageni (Heptageniidae) and the plecopteran Pteronarcella badia (Pteronarcyidae) were size dependent, as there was an inverse relationship between body size and survivorship. These results may have important implications for setting water-quality criteria for metals and For using benthic invertebrates in biological assessments. "

Abstract: " Before treatment with a 3 mg/1 Noxfish (0.15 mg/1 active ingredient; rotenone) for 48 hours, benthic invertebrate communities were quantitatively sampled with a modified Surber net. Then spring, summer, and fall post-rotenone samples were taken monthly at each of four Strawberry River stations for five years. Statistical analyses of the data indicated that the application of rotenone had a significant effect on the following species density: Cinygmula sp., Pteronarcella badia, Hesperoperla pacifica, Hydropsyche sp., and Brachycentrus americanus. Thirty-three percent of the benthic invertebrate taxa at the four stations showed resistance to rotenone. Up to 100% of Ephemeroptera, Plecoptera and Trichoptera species were missing after the second rotenone application. Forty-six percent of the taxa recovered within one year, but 21% of the taxa were still missing after five years. Of the 19 taxa still missing, 47% were Trichoptera, 21% were Ephemeroptera, 16% were Plecoptera, 11% were Coleoptera, and 5% were Megaloptera. "

Quote from page 611: "The reference site was represented by a diverse fauna of stoneflies (approximately fiften species) with similar relative abundances. However, only rare individuals of Amphinemura banski), two chloroperlid, and three isoperlid species represented the stonefly taxa at the regulated site. A general reduction in stoneflies and the occasional appearance of Amphinemura and Isoperla is common below dams in Colorado (Ward and Short, 1978; Zimmerman and Ward, 1984). Eight stonefly species were collected at the recovery site; however, only two (Amphinemura banski and Pteronarcella badia) were consistently represented in samples."
