Female Suwallia pallidula (Sallfly) Stonefly Adult Pictures

 A large number of photos from the microscope allowed a fairly confident ID on this one, which not coincidentally matches very well a previous specimen of Suwallia pallidula that I collected in Washington.

This stonefly was collected from Mystery Creek #237 on August 1st, 2020 and added to Troutnut.com on August 18th, 2020.
