Isogenoides hansoni (Appalachian Springfly) Stonefly Nymph

View 11 PicturesThis large Perlodidae stonefly was a strikingly bright yellow color, more so than any other insect I've seen. I didn't enhance it much. See the discussion threads to follow how we identified this specimen, which was listed incorrectly for several years.

Isoperla (Stripetails and Yellow Stones) Stonefly Adult

Most often it describes the last nymphal or pupal skin exited during emergence into a winged adult.) it emerged from. I was surprised by just how light it was shortly after emerging. I photographed it a couple days later when it had darkened considerably; it was a pale, almost pastel yellow at first.
