Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large Brown Trout that only touch streamers for the rest of the year.

Male Rhithrogena hageni (Western Black Quill) Mayfly Spinner Pictures

I collected this spinner from the trail (old logging road) above a whitewater canyon on a small stream in the Cascades. I'm using its positive ID to put a species ID on a female dun and [speclink id]1217]mature nymph collected on the same trip.

This mayfly was collected from Mystery Creek #249 in Washington on July 4th, 2020 and added to Troutnut.com by Troutnut on July 12th, 2020.
