The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

We were lucky to be able to fish through this storm as it skirted around us to the north, giving us just enough clouds to prompt a BWO hatch but keeping the lighting at a safe distance.

This dun emerged from a mature nymph on my desk. Unfortunately its wings didn't perfectly dry out.

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.

I collected this male Hendrickson dun and a female in the pool on the Beaverkill where the popular Hendrickson pattern was first created. He is descended from mayfly royalty.

Got to experience my first hatch of these flies on a stream where they aren't listed as having them present. Didn't last too long. Took place at 9:30 am and lasted about 30 minutes. Fish didn't rise to them during the hatch but I couldn't keep them off of a #18 BWO later in the day.

I love fly fishing and fly tying more than a fat kid likes cake...

Welcome back to the forum, Mark!

Assuming your comment that this hatch isn't listed is based on angling sources and not scientific lit, your observations may point out the reason. It's my experience that there are often dozens of mayfly species on any given river that go unreported on angler "Hatch Charts", simply because they never seem to offer obvious angling opportunities. From time to time, though...:)
