Pictures of 184 Mayfly Specimens in the Family Heptageniidae:
Male Nixe inconspicua Mayfly Dun
View 13 PicturesThis pretty little dun was part of a sparse midsummer evening hatch on a large Catskill river.
I could not identify it by following a species key step by step, but I tentatively keyed it to the genus Nixe, and based on distribution maps and physical descriptions the most likely species is Nixe inconspicua.
Maccaffertium ithaca (Light Cahill) Mayfly Dun
View 9 PicturesThis dun emerged from a nymph in one of the bowls on my table while I was sorting. I photographed it with the nymphal shuck (Shuck: The shed exoskeleton left over when an insect molts into its next stage or instar. Most often it describes the last nymphal or pupal skin exited during emergence into a winged adult.), and it seems to be of the same species as a nymph I photographed from the same sample.
