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 resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.
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 sky was the perfect scenic complement to the wide-open marsh where we were pike fishing.

Talk about a bad hair day.  This chartreuse/everglow deceiver had been through about 15 northern pike already.

I took this picture after midnight, when the pike fishing was still hot.

This specimen was the first record from Montana and the first record from the mountain west except Alberta where it was first described. It was found in temporary ponds.The nymph has double gills on all segments. The abdominal stripe is an important feature for identification
