Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

This Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.
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,
