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.

With a bit of help from the microscope, this specimen keys clearly and unsurprisingly to Hydropsyche.
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 job is: A hundred days on the side of the river, from the snow melt in early june, to the first snowfall early september!I've found and brought back a couple mayflies(117 of them) from the Mckenzie River in Labrador.

This to explain that I have barely no clue of the water temperature or the date I have caught this specimen. (Note that the two front legs were ''lost'' during manipulation after some pictures)

If you need zoom or other angle let me know!

Thanks for your help guys!

Hi Jean-Philip-

I believe this female imago to be of genus Leucrocuta.
Best regards,
Roger Rohrbeck
