This specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.

It's always a bit hard to be sure when a nymph's out of the water, but this looks to me like a small Isonychia mayfly nymph, like this one.
