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 wild-looking little thing completely puzzled me. At first I was thinking beetle or month larva, until I got a look at the pictures on the computer screen. I made a couple of incorrect guesses before entomologist Greg Courtney pointed me in the right direction with Psychodidae. He suggested a possible genus of Thornburghiella, but could not rule out some other members of the tribe Pericomini.

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.

about two years ago i was fishing in the lower hudson valley of new york, a small streem that flows into the hudson river. it was the 2nd week of feburary when i landed a strange looking trout/salmon. she was silver whith a bright pink stripe, no spots and full of eggs,about 14"-15". on the next cast i landed a male brook trout about the same size. what kind of fish was it? do some fish change how they look in the winter months?
any ideas please let me know.
thanks, thom

I'm not totally for sure on what type of fish it is but I do know that there was a fish some people in Mexico got that had the genetics of a rainbow trout and of a steelhead trout. my best guess is that it could be a cross breed. But then again I am only guessing.

Thom, I'm stumped. I've caught some lake-dwelling rainbows that had very small indistinct spots, but I've never seen a rainbow without spots (except for those yellow cartoon rainbows that states like PA use as stocking "indicators"). Then again, if the fish swam up from the Hudson, who knows? Maybe it passed under the outfall pipe of a carbon tetrachloride plant and had its spots removed! :) (Sorry, but I couldn't resist. Both of the fish you describe certainly qualify as pretty unusual specimens, especially for a lower Hudson trib in February.)
