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

Sorry for the spelling mistakes. I guess I am not a very good proof reader.

In need of some names? Ok... the top one is Lenny. The bottom one is Bob.

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.

Jason and Jummbeau, based on the brown hind wing, I'd guess that "Lenny" is Siphlonurus mirus.

Thank you very much for your replies. Thank you also for giving me a good laugh. I made a pattern for the first mayfly, now it has a name "The Lenny".
