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.

This was the hatch of the night on 25 May 2011. It was epic....yet nothing was rising or visibly feeding. Not really positive what it is. It could be a Hendrickson, it's just so dark and eyes are so red. All the bugs coming off had the same strikingly red eyes.
Thanks all
