Green drake? Grey drake?

It does look like the Flavs that I've seen over at the Metolius...

SquatchHunter-

I believe your mayfly to be a female Ameletus subimago, commonly referred to as a Brown Dun. There are at least (11) Ameletus species known in Montana, many of which are not described in flyfishing entomology literature.
