Black & White Mayfly Nymph - Rhithrogena
Georgia, USA

Size: 1/4"
I found this in a small mountain trout stream in North Georgia. Any ideas on id? Thanks

Moved from Mayflies.

Hi Allen-

Yes, it is surely a Heptageniid, and I believe it to be of genus Rhithrogena. Although probably not the same species of Rhithrogena as yours, this one has much the same light/dark dorsal coloration pattern as yours does.

Incidentally, when you posted the image on Troutnut in early May, Luke Jacobus (the new steward of Mayfly Central) commented as follows: Beautiful. This looks to me like some freshly molted Rhithrogena that I've seen from the SE. The spots on the femora aren't as prominent as usual, but I think I can make them out.
