I'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 smaller one that I photographed. They were outnumbered by the "normal" Ephemerella subvaria nymphs in the sample.
This mayfly was collected from Salmon Creek on March 29th, 2005 and added to Troutnut.com on April 7th, 2006.

Has anyone else seen a Hendrickson nymph like this? 14 Replies »
I found a few of these this spring in just one small Finger Lakes tributary, mixed in with various normal-looking E. subvaria nymphs. The unusual characteristic is the pale prothorax -- the "white collar" segment just behind the head. I've never heard of that color configuration before. Has anyone else?ReplyHendrickson nymph 3 Replies »
Maybe they're mayfly clergy...

This photo shows the light band on the top of the subvaria nymph. The lighter collar seems to be abnormal, or at least an unusual color variation, if I remember the previous discussion on this photo. Reply
I just noted the photo of the bug's belly. It appears solid brown, much to my surprise. Hmm. . . Gonzo? I believe he's away for the holidays, but I'll be interested in his answer on imitating this and other nymphs.
I've navigated away from the photo of the subvaria's underwater on the rock, but they are awesome too.
