Cinygmula reticulata (Western Ginger Quill) Mayfly Nymph
I collected several live specimens of nymphs and reared them to the imago stage. They were C. reticulata. The interesting thing is they were collected in May and were emerging along with Rhithrogena (March Brown). This seems to be an overlooked hatch since in some rivers it emerges very early, before runoff.
