This seems to be a young larva of Limnephilus. Although not clear in the picture, several ventral abdominal segments have chloride epithelia.

Stonefly Species Pteronarcys dorsata
These are often called Giant Black Stoneflies.
This is the largest common eastern stonefly. It's quite abundant in places, but not to the extent of its western counterparts, and since most of its activity is at night it is generally less important. Nevertheless, nymph imitations produce some very large trout, and lucky or very locally knowledgable anglers may find good fishing to the egg-laying adults.
