Return of the Blues

Yesterday spotted the first damsel flies of the season around the garden pond. I usually see quite a few blue tailed and the odd common blue. This time there were three Common Blue Damsels chasing each other about:

  

I also saw a lone tadpole swimming about. It was quite small so not very old. The puzzle is, what type was it? It is ages since the frog spawn developed so we are left with toad or newt. I haven't seen any toad spawn. The newts lay single eggs under the leaves of aquatic plants so I wouldn't notice those.
