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.

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.

This one actually had a medium tan body when it emerged. By the time I took the picture it was dark as night. I was actually looking through my box of specimens trying to figure out where that tan one I caught disappeared to. Then I realized this is it.

Yes. We have incerta, nigra, and blacki in PA. I'm pretty sure incerta is also found in NY.

Folks - This is another I would call Brachycentrus. You can definitely see the maxillary palps folded up in front of the face.

And a note on Apatania - the eastern species are down to two - incerta and nigra. A.blacki, praevolans and rossi were all recently sunk under A. incerta. (Flint 2007 Proc. Ent. Soc. Wash. 109(3):739-740)
