Maccaffertium vicarium (March Brown) Mayfly NymphMaccaffertium 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.
