The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
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.

Thought I'd put these up in case anybody wanted to look at them. They're from this year, around August. The cases were found on medium to large cobbles in fairly calm areas.

Paul,
Thanks. I saw these and couldn't resist the opportunity to record the different pupal stages.
Eric,
I'm sure you don't have the genus in PA. There are two species in the U.S. from what I understand. M. nobsca from Texas and M. flexuosa from California, Arizona, Texas and Arkansas.
Edit: A further look at range maps shows M. flexuosa in New Mexico, Oklahoma, Missouri, Indiana, Vermont and Ontario. And that's just as far as the U.S. and Canada are concerned, looks like it's common in Central and South America as well.
