Maine Posts: 3	Can anyone help with these two Mayflies? Both pictures were taken on June 17th, 2007 on Jam Black Brook in Appelton, Maine. The brown one is about a size 14 and the green one is about a 12/10. The brown one has 2 tais and I can't remember how many the other one had. Any assistence would be helpful. Thank you in advance, Jeff Space

As for species, I think the bottom one is some species in the Siphlonurus genus (gray drakes), though I couldn't tell you which one. The top one might be in that genus, too, but I don't remember there being a species with that coloration in the spinner's hind wing.
