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 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.

Guys, Sorry. For some reason I'm having a heck of a time posting the photo of the bug for you to ID. Didn't mean to post the first one without a photo and certainly didn't want to post the blank above. Rats.
Anyway, if you want to view the insect get on TroutUnderground.com and search for the post about Bitterroot Skwallas and what I've been calling Ameletus mays. It appeared last Spring. Got a nice picture of a dun on a cork handle that should provide enough diagnostic clues.
