Ewwww, yucky little buggers. I have never seen mosquito larvae before. Do you have your pond circulating? I thought mosquitos didn't lay eggs in water that is moving. I've never had them in my pond.
If you are seeing something crawling in the bottom of your pond that looks like it is straight from a horror movie, it might be a dragonfly larvae. www.thomasames.com/insects/other/dragonym.jpg
We've had these in our pond and scared the daylights out of me at first.
