Suwallia 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.
