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.

Started fishing at 7am, and hooked three pretty quickly on a BH Pheasant Tail 16. Around 9 am the nymphing seemed to fall flat, I tried a variety of patterns and sizes but was unable to catch any more fish. The fourth fish was caught on a BH Wooly Bugger 6 (Black), which I tied on after watching my buddy (who fishes spin reel) catch a couple with his Mepps Aglia. First cast, and bang, rainbow!! Overall a great day on the water. Especially because the fly guy beat the spin fisherman in the un-official contest that we perpetually engage in. Good Times.
