Blue-winged Olives
Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Looking at the above pics of hexagenia duns and having seen millions of them on the water live, it strikes me again and again that the great majority of all the mayfly type duns sit there (perhaps not long)not with their wings spread but with them resting upright against each other. The Brit Oliver Edwards acknowledges this in his "cut-wing dun" pattern stating that it is a very sturdy fly which also cuts down on the nasty propellering habits of the partially spread wing tied dun pattern. So why is the traditional dun wing tying position so strongly adhered to?

Jason's hexagenia dun photos are excellent examples, also see Oliver Edwards' "FLYTYERS MASTERCLASS".
