Mayfly captured in the Black River, northern Michigan on June 7. Can anyone tell me the name of this bug? Thanks, Lev

Looks to me like a Leptophlebia...cupida or nebulosa...Though I've never seen the odd dark markings on the wing?

We call it the Borcher's Drake...Thought to be the model for Ernie Borcher's famous Au Sable fly.

It looks like a male Isonychia tusculanensis imago, but they're not supposed to be in N. MI. Leptophlebia nebulosa looks very similar and does have the brown tipped wings as well. They have a terminal filament that I'm not seeing though. Even so, nebulosa is found in MI, so that would be my guess. Perhaps the middle tail was knocked off as these guys are always losing tails.

Gentlemen, you guys are great. I do not have other photos, just this one. One of the tails did break off in my fingers. I'll go with the Leptophlebia since the folks at Gates Lodge did mention this off the cuff. If anyone else has a guess please weigh in but I think this case is solved! Thanks.

Nebulosa it is then, Lev.

The brown spot is likely from too much finger pressure on the wings with the hands. That often breaks the veins and lets the fluid out into the wings membrane.

Huh? Were'd you get this from, Mack...:)

Hi Mack,

I too have observed a yellow liquid-appearing spot, usually in the tip of one fore wing, and have often wondered about it, although it never occurred to me that it might be the result of a mayfly having been captured by its wing tips.

However, in the case of Leptophlebia nebulosa , the brown staining on the outer 2/5 of their fore wings serve to distinguish them from other Leptophlebia species.
Best regards,
Roger Rohrbeck
