Hex Mayflies
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.

Holocentropus Caddisfly Larva Holocentropus Caddisfly Larva

Dorsal view of a Holocentropus (Polycentropodidae) Caddisfly Larva from the Yakima River in Washington

This one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.

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.

Got out a little before the Arctic weather hits us here. Plenty of willing fish. A few olives around

Good job, Eric! My fly fishing gear is going to be gathering dust for a few months while the ice fishing gear will be getting dusted off here very shortly. How big was this one and how many others did you tempt up?

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Pretty work, Eric. I had hoped to head over that way Thursday, but fate intervened. Perhaps in a week or so if temperatures permit.

I think that fish was about 15". I caught more than my share of fish.

Louis, the forecast looks like it's enough to keep me inside for at least this week. Too cold. May keep the crowd down though. I think the weather we got on Thursday and Friday helped me out. It gave those fish a bit of a respite from other anglers. You could tell. They were pretty content for the most part.
