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.

Hi Jason,

Looks like below the fast water on powerline pool but just above the bend on the Willi with the Quickway up on the ridge in the background.

Good job Junior! I had my eyes glued to an Ebay auction I was following today and didn't get a chance to see that Jason was running the "Name that Spot" thread. That is the sectionof the Willow that I first fished back in 1970. I used to park my 1969 VW Campmobile under the power lines right up at the rivers edge and stay there all weekend.

Catskill fly fisher for fifty-five years.

Yeah, this is a pretty recognizable spot. I figured the angle and narrow field of view of this picture might make it a little bit trickier to guess, but you guys know that river too well!
