Ephemeroptera, an exuvium, indeed. Note that these mayflies - and this is only true for this insect order - have a molt after leaving water and soonly thereafter another. After the first they become subimagos, after the second thy are called imagos. Then they die in a short time. I think there's very little chance to ID without seeing an imago or subimago itself.
