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.

So i just wanted to inform anyone who might be searching for good deals on hand crafted flies - that i am running a sale from the 1st of December to Christmas Eve. The sale will knock 10$ off any order placed for 40$ or more, and 20$ off any order placed for 80$ or more. These flies could make for great presents to fellow anglers, or even be a good way of saving some money while re-stocking your fly boxes with some new patterns. If your interested send me a private message here on Troutnut or shoot an email to jesse.filingo@filingoflyfishing.com
