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.

A small, old rock wing dam has created an excellent riffle and pool in this classic trout stream.

I just found a really funny article by some retired doctors who ran an amusing experiment on the chalkstreams to see if fish really have a preference for certain flies. Of course, they did. Check it out.
