Ephemerella subvaria (Hendrickson) Mayfly NymphEphemerella subvaria (Hendrickson) Mayfly Nymph View 2 PicturesI've never seen this strange coloration on any Ephemerella subvaria nymph in a book before, but it's similar to several other specimens I collected on the same outing, including a larger one that I photographed. They were outnumbered by the "normal" Ephemerella subvaria nymphs in the sample.

Rhyacophila vocala (Green Sedge) Caddisfly LarvaRhyacophila vocala (Green Sedge) Caddisfly Larva View 11 PicturesThis specimen is very tentatively placed in Rhyacophila vocala, but see the caveats given by Dave Ruiter in its identification: "There are two species (hyalinata and vocala) currently within the group and this looks closest to R. vocala. It is likely, however, there are several undescribed species in the group and this is one of those."
