Stenonema femoratum
Hi Todd-

I believe this female subimago to be Stenonema femoratum.

The nymphal photos are not useful for identification purposes, as the nymph was not submerged in water while being photographed.

Next time, you might want to take along the lid of a small jar, which has a light background inside it, and place the nymph in the lid. And then, fill the lid with sufficient water to fully submerge the nymph before attempting to photograph it. Otherwise, most of the body appendages simply won't display themselves.
