Suwallia pallidula (Sallfly) Stonefly NymphSuwallia pallidula (Sallfly) Stonefly Nymph View 6 PicturesThis specimen keys out to Suwallia, for which I did not find any nymph species keys. However, I'm placing it in Suwallia pallidula because I caught a few adults in the same spot that closely resembled the abundant nymphs and keyed them out to species. Features I noted under the microscope when keying this specimen to genus included apical (Apical: Close to the apex; tip or end.) hairs of cercal segments that were directed at posterior (Posterior: Toward the back of an organism's body. The phrase "posterior to" means "in back of.") angles, and the longest apical (Apical: Close to the apex; tip or end.) hairs of distal (Distal: Far from the point of attachment or origin; near the tip.) segments were shorter than their following segment.

Female Suwallia pallidula (Sallfly) Stonefly AdultFemale Suwallia pallidula (Sallfly) Stonefly Adult View 9 PicturesI collected a few of these throughout the afternoon. The positive ID on the adults allowed me to also put a species ID on the nymphs.

Female Suwallia pallidula (Sallfly) Stonefly AdultFemale Suwallia pallidula (Sallfly) Stonefly Adult View 12 PicturesA large number of photos from the microscope allowed a fairly confident ID on this one, which not coincidentally matches very well a previous specimen of Suwallia pallidula that I collected in Washington.

Male Chloroperlidae (Sallflies) Stonefly AdultMale Chloroperlidae (Sallflies) Stonefly Adult View 4 PicturesThis specimen unfortunately was blown away by the wind mid-way through the photographs, so I wasn't able to preserve it for an ID or get some of the other angles.

Female Suwallia pallidula (Sallfly) Stonefly AdultFemale Suwallia pallidula (Sallfly) Stonefly Adult View 6 PicturesI didn't key this one out under the microscope, but I just keyed a similar one from Montana and this one matches the macroscopic appearance closely enough that I'm guessing it's the same thing.

Kathroperla perdita (Sallfly) Stonefly NymphKathroperla perdita (Sallfly) Stonefly Nymph View 1 PicturesThis species is uncommonly collected except from wells. It is a hyporheic species living in the river gravels of river floodplains until it is ready to emerge.
The head shape is an important identifier.
