The Specimen

Rhithrogena impersonata (Dark Red Quill) Mayfly NymphRhithrogena impersonata (Dark Red Quill) Mayfly Nymph View 6 PicturesThis was the only Rhithrogena specimen in a large sample of nymphs from a small Catskill stream. It looks virtually identical to Rhithrogena impersonata specimens collected in the Midwest, but I didn't get to check the distinguishing features under a microscope.
Collected April 19, 2006 from Mongaup Creek in New York

Kinza-

Possibly, if the photos are good and show distinguishing characteristics.

Are you sending adult or immature specimen photos?
General location is somewhat helpful as well. I'm assuming North America here, so NW, SW,MW,NE,SE.

If you are sending photos of the nymphs, the following is helpful (necessary for a confident identification):

1.a good ventral photo of the abdomen
2. A good dorsal photo of the abdomen with gills plainly visible
3.A good photo of the terminal abdominal segment with caudal filaments visible
4.A good Dorsal photo of the head
5.Fairly detailed photos of gills on segments 1-6.
