Ephemerella needhami (Little Dark Hendrickson) Mayfly NymphEphemerella needhami (Little Dark Hendrickson) Mayfly Nymph View 5 PicturesI took quite a few notes at the microscope when I collected this specimen. They're attached to the appropriate pictures.

I found this specimen in the same collection as a similar one. Since I only have strange views of this one, it's possible that they're actually the same specimen and I somehow confused my picture-ordering and got the impression that they're different nymphs.

Ephemerella needhami (Little Dark Hendrickson) Mayfly NymphEphemerella needhami (Little Dark Hendrickson) Mayfly Nymph View 5 PicturesThis specimen strikingly resembles another specimen from about 1300 miles away in the Catskills, which I tentatively called Ephemerella aurivillii. This one has much more prominent abdominal tubercles (
A few (not all) of the abdominal tubercles on this Ephemerella needhami nymph are circled. They are especially large in this species.

Tubercle: Various peculiar little bumps or projections on an insect. Their character is important for the identification of many kinds of insects, such as the nymphs of Ephemerellidae mayflies.). It may be that they're both the same species and I don't have my identifications straight.
