I found a couple of these larvae yesterday scrambling around in the shallow waters of a creek here in the Poconos. I would say they are a bit over a ½ inch. Sorry the photographs are so blurry but they were taken just before sunset and my camera doesn't do well in low light conditions. Anyone have any idea what species these are?

I posted this on another website but I think I stumped them. I'm hoping someone here might have some ideas!
