Pictures of 24 Mayfly Specimens in the Genus Cinygmula:
Cinygmula subaequalis (Small Gordon Quill) Mayfly Nymph
View 3 PicturesI had heard reports of a bright red heptageniid nymph before but never seen one until I found this early instar (Instar: Many invertebrates molt through dozens of progressively larger and better-developed stages as they grow. Each of these stages is known as an instar. Hard-bodied nymphs typically molt through more instars than soft-bodied larvae.) specimen in a very high water quality small stream in the Catskills. Cinygmula 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.
