Female Hesperoperla pacifica (Golden Stone) Stonefly Adult Pictures

 My blurry photo at first makes it look like there might be a distinct notch in the subgenital plate of this specimen, but that's not the case -- just a poor photo. That's important to the ID.

This stonefly was collected from the Gallatin River on July 2nd, 2019 and added to Troutnut.com on July 18th, 2019.
