Female Ephemerella excrucians (Pale Morning Dun) Mayfly DunFemale Ephemerella excrucians (Pale Morning Dun) Mayfly Dun View 12 PicturesThis "specimen" is actually two different duns, one missing the middle front and back left legs, the other missing the terminal filament i.e. middle tail. I added them together by accident, but since they're the same species, stage, and gender, I might as well leave them together.

Cinygmula (Dark Red Quills) Mayfly NymphCinygmula (Dark Red Quills) Mayfly Nymph View 5 PicturesThis nymph was one of several mature Cinygmula nymphs collected at the same time as this female dun emerged, so they're probably the same species.
