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.

No problem Paul, for the record I'm going to say it was a cutty, a unique one.

Beware: There were a lot more footsteps before us than we may realize. Most high mountain lakes and upper tribs never had fish in them of any kind, until people started hauling them up in buckets, and not keeping records, and later by airdrop. There are precious few (if any) places left that fish aficionado's (of many ilks) haven't messed with things. We can consider nature's order pretty much "messed with" across the board.

Unless you run with Bigfoot, Paul, like my nephew does. Those hairy beasts know where all the natives are and I have it on good authority that they scared away any humans carrying phony fish into their domain.:)
