Female Rhithrogena virilis Mayfly Dun Pictures



 I'm guessing this one is Rhithrogena virilis based on collection of a male spinner of similar size and body configuration during the same trip.

This mayfly was collected from the South Fork Snoqualmie River on June 16th, 2018 and added to Troutnut.com on June 23rd, 2018.
