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.

We were lucky to be able to fish through this storm as it skirted around us to the north, giving us just enough clouds to prompt a BWO hatch but keeping the lighting at a safe distance.

This dun emerged from a mature nymph on my desk. Unfortunately its wings didn't perfectly dry out.

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.

My name is Leonardo García, I am a biologist intern in the National Autonomous University of Mexico and I'm doing my thesis with title "Morphological variation in the genus Caecidotea isopods (Packard, 1871) (Crustacea: Peracarida: Isopoda) of Mexico." Inside the National Collection of Crustacean, Biology Institute (UNAM).

I was wondering if somebody can help me to get some specimens of the specie Caecidotea communis and send them to me to continue with my thesis work. It would help and enrich my study.

Thanks for your attention

Leo
