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.

This porcupine seemed to be feeding on the filamentous green algae that had accumulated around the tip of a fallen cedar sweeper on a classic piece of northwoods trout water.
Look at the hole in that thing's mouth... no wonder mergansers are a threat to trout.
These baby Canada geese are just beginning to grow their real feathers.

This is the skin a brown drake dun shed when it molted into a spinner.  Many of these were on the surface one afternoon, having been blown in after the flies molted on overhanging alders.  They were our most noticeable sign of an intense brown drake hatch the previous night and a spinner fall to come.
