This dun emerged from a mature nymph on my desk. Unfortunately its wings didn't perfectly dry out.

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.

Fishing last Sunday on a spring creek to be left nameless, my buddy and I came to a pool where the trout were slashing and leaping out of the water chasing something. Typical Caddis activity right? We saw no adults on the water. or escaping into the air. Any other bugs that the trout would be chasing like that. This was around 11am to 12:30 pm. We then encountered the same type of action later in the evening around 6 pm to dark. Would the be chasing tiny emerging midge pupa so aggressively/

Rjpcaddis-

It is named the Mystery Hatch!

Seriously, frantic feeding activity likely means the trout were chasing something reasonably elusive. It could have been insects making trial trips toward the surface film, but not actually yet ready to emerge. Some insects will do so for several days prior to emergence.
