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.

This specimen keys pretty easily to Onocosmoecus, and it closely resembles a specimen from Alaska which caddis expert Dave Ruiter recognized as this genus. As with that specimen, the only species in the genus documented in this area is Onocosmoecus unicolor, but Dave suggested for that specimen that there might be multiple not-yet-distinguished species under the unicolor umbrella and it would be best to stick with the genus-level ID. I'm doing the same for this one.
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.

Two dear make tracks across a frozen trout stream in the deep snows of early February not far from Lake Superior.  I had hoped to sample nymphs in the stream (which later turned out to be quite fertile) but it wasn't open.

Here's another of my very frigid early nymph sampling sites.
This tiny spring creek is extremely fertile, and I sampled many interesting insects I didn't find anywhere else.  The water was completely open even though other nearby spring creeks were frozen over and the snow was three feet deep.

I had hoped to sample some nymphs here, but I didn't bring an ice auger.
