Cinygmula reticulata (Western Ginger Quill) Mayfly NymphCinygmula reticulata (Western Ginger Quill) Mayfly Nymph View 1 PicturesI collected several live specimens of nymphs and reared them to the imago (Imago: The sexually mature adult stage of the mayfly is called the imago by scientists and the spinner by anglers.) 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.
