Another i.d. challenge

I was trying to get a decent photograph of a damselfly at lunchtime today and came home thinking I'd got loads of pictures of it. When I viewed them just now I realised there were three different insects: a blue tailed-damselfly male, a female of the same species, and this.

Blippers responded brilliantly to my plea for help with the moth in my garden last weekend - can anyone help me out here? I think it might be a common blue damselfly but I'm bothered by those whitish legs.
