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.

When asked what I just caught that monster on I showed him. He put on his magnifiers and said, "I can't believe they can see that."

Flags,

You asked, 'What are DST Quills'? Well, they are not turkey biots or turkey anything. I should know since I developed them. I'll not tell you what they are but I'd be more than willing to send you some samples. Oh, here's a photo of an Olive tied with DST Quill body.

and a Red Quill

and an extended body Potamantus

Oh, I just looked at the fly you referred to. I believe it's a fly that I tyed and Hans photo'd for his site.

Ok. What does DST stand for then? If not what Allan (Falsifly) stated?
