Alloperla (Sallflies) Stonefly Adult
View 6 PicturesThis specimen was completely green when I collected it from among many others gathered on a midstream rock along with their nymphal shucks (Shuck: The shed exoskeleton left over when an insect molts into its next stage or instar. Most often it describes the last nymphal or pupal skin exited during emergence into a winged adult.) early in the morning. There was also a yellow one with them, which I assumed was a different species. Now that I've seen how this one started changing from green to yellow, I have to wonder if they weren't the same species and the yellow one was just older.
