Stonefly nymph

Stonefly nymph
Lancaster County, Pennsylvania, USA
March 11, 2016
Found submerged under rock in swift-flowing Kelly's Run (freshwater stream) but rock was to the side where water wasn't flowing as swiftly. We managed to get only one picture. My impression of nymph was that it was about an inch long. We were geocaching and not bug-observing.
