*shock horror* where have all my tadpoles gone? This is what the edge of the pond used to look like in April...

I spotted some after a while, but their behaviour has changed. they used to spend lots of time in the shallows, but now they're all at the bottom of the pond, lying low.
And then I saw the culprits, circling in the water, darting around looking for their next snack. Dragonfly larvae - the sharks of the garden pond.

This isn't my pic, I googled it, but I saw four or five of these hungry beasties. I hope we'll spot them emerging, and I hope they'll leave at least some taddies behind, I want froglets!
