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.

This little pool in update New York is enjoyed by many tourists every day, and it still holds a few trout -- stockers mostly, but you can't complain about the setting!

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.

Eric,

You didn't show me that 2nd pic there...the so-called Great Speckled Olive, but where's the olive? The Pseudo-Gray Drake...I told you that the local Grayling Boys (read Tim Neal here :), once they see this one, its hard to get them to tie something on smaller than a size 10, for the rest of the season! :)

Maybe Tim will add something here, but they have a rep for being showy in the mating swarm but not falling en masse. We all know that they have to come down, these bugs don't have the stored energy to fly around, and not get it done...The fish have only one problem with them, letting them float by unmolested. ;)

Seeing one coming downstream, early in the season, can get your heart pounding! At first you are not sure your eyes aren't playing tricks on you.

Great pics, BTW!!!

many times they don't even have to be on the water for the fish to try and eat them, they leap into the air to try and catch one. They must taste much better than chicken.

Thanks Paul, but I'm thinking I should get models with only two legs...

You guys are making me envious...I'm not seeing hardly any flies on my local waters yet! Not even Hendricksons or Early Brown Stones...

P.S. Beautiful photos!

P.P.S. "Real men nymph." Guess I'm not a real man, then. My nymphs just all seems to hang up on the bottom, so I don't...nymph, that is...

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
