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.

Dorsal view of a Skwala (Perlodidae) (Large Springfly) Stonefly Nymph from the Yakima River in Washington

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.

The pictures aren't nearly good enough for me to actually follow a key, but I'm pretty curious. This species was out in smaller numbers alongside prolific Brachycentrus flies. Based on the long antennae I'm going to initially guess Leptoceridae, but I don't think that's right. It just doesn't look like the other Leptoceridae on this site, and then antenna, though long, aren't as long as theirs.
