They’re not green drakes, there hecubas.  At least that’s what I told the guy who was arguing that he had been seeing lots of green drakes on the Flathead lately. Another guy told me they were sulphers. Anyway, here are a couple images. Photos are borrowed from and where you can geek out on all sorts of bug stuff.

Mohogany dun - brownish - size 12-16

Hecuba - tannish olive with burgundy rib - size 12-8

Sulpher Dun - yellow - size 12-14


Plenty of these bugs on the Blackfoot, Clark Fork, and Bitterroot lately but I was up the Middle Fork a week ago and found several hecubas and Mohos up there too.
