Pycnopsyche guttifera (Great Autumn Brown Sedge) Caddisfly Larva Pycnopsyche guttifera (Great Autumn Brown Sedge) Caddisfly Larva

This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.

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.

Lately I've become interested in water pennies, though I can't say why. Is a water penny nymph fly in my future?

Anyway, I took this picture today. It is a live specimen that I collected from Trout Creek, which flows into the Cannonsville Reservoir / West Branch of the Delaware river in New York in October 2013. It's current home is a 2 gallon aquarium it shares with some common stoneflies. I used a 50mm macro lens on a Cannon EOS camera with brown felt as the background. I made a special "V" shaped micro aquarium for it so that it would attach to the side wall and not the bottom so that I could get this picture.
