27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

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.

Nice Mark.I've never seen that one here in PA only Psilotreta. Pretty sure we don't have the genus.

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.
