Epeorus vitreus (Sulphur) Mayfly Nymph
View 3 PicturesI suspect this is an Epeorus vitreus nymph. At the current 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.), it's tough to make out the pair of dots on the tergites (Tergite: The top (dorsal) part of a single segment on an insect's abdomen when it consists of a single chitinous plate (sclerite), or an individual sclerite if the segment has more than one.) which signify that species, but with zooming and contrast enhancement they become evident. Epeorus pleuralis (Quill Gordon) Mayfly Nymph
View 4 PicturesThis Epeorus pluralis dun is recently deceased in these photos. I decided not to photograph several lively, less mature nymphs. This one was ready to hatch, as indicated by the black wing pads (
Wing pad: A protrusion from the thorax of an insect nymph which holds the developing wings. Black wing pads usually indicate that the nymph is nearly ready to emerge into an adult.). I believe it had not been dead long enough to lose its natural coloration.
The wing pads on this final instar Baetidae
mayfly nymph are extremely dark.
