Bug experts: I need advice

Can anybody shed some light on what this might be? September, Gallatin River, Montana.

Green drake? Grey drake?

Too bad the lighting isn’t better.

Any help would be great!

As always, i appreciate it!

i think that you were right with the gray drake but im not real sure

flav?

I think it’s a Gray Drake. www.troutnut.com/specimen/242

I agree with DShock Gray Drake, what size 10, 12 ?

Yeah, somewhere in there.

I appreciate the help!

Adams, size 12. :slight_smile:

It does look like the Flavs that I’ve seen over at the Metolius…

I’m no expert though…and it does look like that picture of the gray drake…

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.
