With a bit of help from the microscope, this specimen keys clearly and unsurprisingly to Hydropsyche.

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.

I'm not sure why I had this specimen in the Baetidae to begin with. The eyes aren't turbinate and the hind wings are fairly large. I'm going to guess Paraleptophlebia at a glance, but I should come back to this one later. Any thoughts?

It's a pity the pictures are so fuzzy and dust-spotted up close. I took this picture before I really learned how to use and maintain my Canon 20D.
