Mayfly to identify...

[pilonm]

Hello all,

Here is the subimago of a Mayfly I photographed last May 7th, 2010 in Quebec, Canada (near Vermont).

Can we identify it? Family, genus, species?

Male or female?

If a structure is missing in order to identify it correctly, let me know as I have other pictures of the specimen, including the final exuvie.

Thank you very much in advance for your great help

Might be a March Brown or Hedrixon. It has small eyes so it is a female. I tie fishing flies so know a little about the may flies of the US.
