That's a good picture, next time try to get a picture of the viens in a
wing, and then go to the website I manage for our flyfishing club.
Roger Rohrbeck has developed an identification scheme that gets you to
the genus for Washington mayflies, and I think that includes most of
what you can find in Montana too.

You mean like this?
http://www.geocities.com/troutbum_mt/wings.html

www.offc.org is the website. Click on the entomology link, and then
the WA Mayfly identification section. The questions are full of
technical terms, but they are all defined on a page also linked to on
the entomology page. Roger is still working on this stuff and would
appreciate any comments anyone has on the page.

VERY useful site. The only thing I would suggest is actual pictures
with the descriptions, which I understand is going to be very hard
to do. Perhaps users can submit pics? Running through the Q&A and
then having possibilities is great and the descriptions are great,
but the lack of an actual pic to confirm is kind of a drag. Having
an actual pic of each would be, to quote a North Dakotan, "the
sheep's ass." g
