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.

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.

Moth Family Geometridae (Inchworms)

These terrestrial moths are sometimes taken by trout when their larvae, the well-known inchworms, dangle by their little silken threads in especially high numbers around June. They may be abundant enough throughout the forest that plenty dangle their way into the water.
