The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

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.

I will be in Bayfield July 24 - 30 related to wedding / family reunion. Would love to pack the gear for fly fishing if I thought any chance of some. I live in SE Minnesota so familiar with small, cold, spring filled creeks. Would love to learn enough in the next couple of weeks to help me decide whether to take the gear along.

Very close to Bayfield you might try the Little Sioux. I caught my first trout there, about a 4-incher when I was probably about 15. I don't remember anything else about it, but I think it has some resident fish. Most of the other creeks in the area should have something, usually small rainbows / baby steelhead. Toward central Bayfield County there are tons of streams to try for browns & brookies. If you like poking around in small creeks and catching small fish in pretty settings, that's a nice area.
