I live in Woodstock, NY on a lake with a stream. In pools around the stream there are 1000s of these of various sizes. They also seem to be undergoing a metamorphosis. Some are inside cocoons made of various elements. They are in the water, mostly, but seem to be able to survive on land.

This is the larva of a Stonefly, known as a Naiad. Their presence in large numbers is a good indication that the stream in which they were found has very low levels of pollution. You can find additional information on Stoneflies on BugGuide.
