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 species was fairly abundant in a February sample of the upper Yakima.

I took these from the mouth of a trout I caught in Oil Creek in
NW PA. I occasionally find these in the mouths of fish in this stream. These bugs were out of water for about 8 hrs when I remembered about them. As soon
as I put them in water 2 of them just took off swimming. The 3rd one had expired. What I’d like to know is: Are these fish food or parasites of some sort? The large one is about a size 18 nymph hook.

I think they may be Argulus americanus. It's a parasite. Further information can be found here;

Thanks so much for the ID. I
Guess I won’t bother trying to tie an imitation.
