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 lead to Couplet 35 of the Key to Genera of Perlodidae Nymphs and the genus Isoperla, but I'm skeptical that's correct based on the general look. I need to get it under the microscope to review several choices in the key, and it'll probably end up a different Perlodidae.

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.

I am considering a trip to Patagonia next spring. I have a choice of the Limay Medio River or the San Martin de los Andes area. With the Limay, I am sort of concerned about the type of fishing....I read in Fly-Fishing in Patagonia, A Trout Bum's Guide to Argentina that the migratory browns only feed about 3 hours per day and it is pretty hard fishing--windy with lots of sinking line fishing. And that it is a river for trophy fishing, not consistent action. While I'm sort of worried that the San Martin area rivers such as the Malleo and the Chimehuin are "crowded" these days. I don't want to go all the way down there and have other fisherman around like I was in Henry's Fork or Yellowstone. And that the "fishing is not what it was" but instead resting on reputation. Does anyone have any recent experience with these areas and some advice? The San Martin trip is in mid February and the Limay trip is in mid March. Thanks!!!
