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 (Dorsal: Top.) bump on the claspers (Clasper: The claspers, also known as forceps, are a pair of appendages beneath the tip of the abdomen of male mayfly adults, which are used to grab onto the female while mating.) just isn't present.
This mayfly was collected from the Middle Fork Snoqualmie River on August 4th, 2019 and added to Troutnut.com on August 5th, 2019.
