This was the only Rhithrogena specimen in a large sample of nymphs from a small Catskill stream. It looks virtually identical to Rhithrogena impersonata specimens collected in the Midwest, but I didn't get to check the distinguishing features under a microscope.

This mayfly was collected from Mongaup Creek on April 19th, 2006 and added to Troutnut.com on April 21st, 2006.

This picture shows the characteristic gill structure of the Rhithrogena genus more clearly than the mature specimens of Rhithrogena impersonata that I collected back in the Midwest. The "suction cup" gill structure is an adaptation to help the nymphs cling tight to rocks in fast water.
