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.

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 Chloroperlidae (Sallflies) Stonefly AdultFemale Chloroperlidae (Sallflies) Stonefly Adult View 6 PicturesI wasn't able to confidently ID this one beyond family without a better microscope than the one I have, but Suwallia is a likely possibility for the genus.

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.
