Ephemerella aurivillii Mayfly Nymph
View 3 PicturesThis specimen seems to be morphologically identical to the darker specimens of its species, but it's a very distinctly different color. I'm guessing this is a gender difference, just as I've guessed for the similar E. subvaria nymphs.

Ephemerella needhami (Little Dark Hendrickson) Mayfly Nymph
View 2 PicturesI photographed three strange striped Ephemerella nymphs from the same trip on the same river: a black and olive one, this one, and a very very striped one. I have tentatively put them all in Ephemerella needhami for now.

Ephemerella (Hendricksons, Sulphurs, PMDs) Mayfly Nymph
View 6 PicturesThis pretty Ephemerella nymph has really weird markings. It has one band on the tibiae (Tibia: A middle segments in the leg of an insect, located between the femur and the tarsus.) and a thin but distinct dorsal (Dorsal: Top.) stripe faded in the center which looks very different from the stripes on Ephemerella needhami and Ephemerella aurivillii. It definitely has the fan tail characteristic of the Ephemerella genus.
