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.

Female Amphinemura (Tiny Winter Blacks) Stonefly AdultFemale Amphinemura (Tiny Winter Blacks) Stonefly Adult View 5 PicturesA few of these tiny stoneflies were among the only species of aquatic insect adults in the air on this particular afternoon, with most of the action coming from a species of Epeorus mayfly. I somehow forgot to photograph this one on the usual ruler, but I recall it was very, very small, with an abdomen no more than 1mm in girth and the body, not counting the wings, probably just 5-7mm long.

I photographed it a couple days later when it had darkened considerably; it was a pale, almost pastel yellow at first.
