Tadpole question.

The best I can surmise from the info that my investigations have turned up so far is that these are probably Toad tadpoles. Toadpoles are black (frogpoles are brown), have a larger head than frogpoles and don't emerge from the pond until about August, (possibly later I suppose considering the poor spring that we had).

Well, that's interesting. Do you know if the large black tadpoles that you still have are Toad tadpoles?

Another thought has occurred to me that with the strange spring we had there may have been two completely separate spawning events. (Istr that the frogs in my pond spawned very early this year).

Although I can't work out why any tadpoles that haven't yet changed are larger; unless they were from the first spawning and the cold spring somehow held up limb development and they have carried on growing whereas any from a second spawning just developed as normal.

I obviously don't know as much about Frogs as my sister had hoped I would!
