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.

Clostoeca disjuncta (Northern Caddisfly) Caddisfly Larva Clostoeca disjuncta (Northern Caddisfly) Caddisfly Larva

This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.

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.

This was identified by Dave Ruiter as Hydropsyche californica or Hydropsyche occidentalis, but the characteristics were not clear enough to tell them apart.

Creno,, thanks for the wonderful pics of the caddis. This is another piece of the puzzle to figure out! I was into caddis on the south branch of the ausable a few weeks ago and did pretty good, although Im still not certain of the variety I was fishing. But a size 14 tan x2 was very helpful!
