This Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.

I am pretty sure this is a March Brown female but wanted to post here to confirm. I caught one with the egg sac hanging out a few minutes before, and then pulled in two mating pairs where the female had this red belly full of eggs. Pretty excited about it! Thanks!
