The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
For a species not yet reported in my state, I've been surprised to find these in two different locations lately. I was tempted to think they're the more common Paraleptophlebia debilis, but the characteristic big dorsal bump on the claspers just isn't present.
This mayfly was collected from the Middle Fork Snoqualmie River in Washington on August 4th, 2019 and added to Troutnut.com by Troutnut on August 5th, 2019.
