Pictures of 59 Mayfly Specimens in the Genus Maccaffertium:
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. Maccaffertium vicarium (March Brown) Mayfly Nymph
View 4 PicturesI photographed this Maccaffertium vicarium nymph shortly after it molted to a new 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.) in my holding container. Many nymphs take on drastically different coloration immediately after molting, and this species is no exception.
