5 Example Specimens
This species of Brachycentrus was extremely common in mid-September kick net samples in the Yakima canyon.
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.
I already had one of these on the site, but these giant Hydropsychidae larvae are just too photogenic to pass up.
