Hexagenia limbata

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.

I just can't convince myself that either of the larvae pictured in this section are Brachycentridae. The cases don't conform to any I know (usually tapered four-sided "log cabin" cases for most Brachycentrus or smaller tapered round cases for Micrasema and Amiocentrus).

You're probably right. These larvae were from the old site and I mostly had identifications based on various helpful emails I've since lost track of. So I don't remember what the rationale was.

That's why the new site has this comment system on the specimens: to keep a public record of the identification talk.

This is another specimen that has bothered me for some time. The fourth picture in the sequence seems to show a dorsal hump. I'm guessing that this is another limnephilid. Creno, help me out here!

Gonzo - Sorry I cannot help much other than agree with you it is not a brachycentrid. Looks like a limnephilid to me. I can't get a good enough view of gills or legs to get any closer.

Fair enough. Thanks, Dave.
