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.

Insect Family Formicidae (Ants)

Ants are one of the best-known terrestrial food sources for trout. Wingless ants often stumble by accident into the water, making them a very common "occasional" item on the trout's menu. Imitations of these unlucky critters make excellent searching patterns in mid- to late summer.

The real fun with ants, however, comes from the mating swarms of winged species. They are spotty and hard to predict, but when they happen to fall over the water they can draw more trout activity than all but the best hatches of huge mayflies.

Formicidae Fly Fishing Tips

Ant imitations are effective above and below the surface.

A heavy fall of ants will make trout extremely selective to their distinct form, and smoothly tapered mayfly imitations in the correct size and color are likely to be rejected on account of their shape.
