Some questions

Matt asks:

M: Do the larvae of Broad-bodied Chasers live in streams?

J: No, they seem never to be found in streams and rivers. Your’s must have come from another pond, lake or very slow moving ditch somewhere.

M: Can sticklebacks live happily alongside other creatures or are they also quite voracious?

J: Lots of animals do live alongside sticklebacks but I think the effect they have will depend a lot on the size of pond. In a local pond down by the river near us in Abingdon, there’s a good range of animals living in a pond that also has 3-spined sticklebacks. But I suspect that when you put the sticklebacks in a small pond they’re likely to have a much bigger impact.

Sticklebacks are notorius for exterminating Great Crested Newt larvae; no doubt they would have the same effect on the smaller newts too. People sometimes go to considerable lengths to get rid of them from crested newt ponds.

    Thanks! I haven’t yet found our local ponds, for instance to perhaps find some plants to bring a little home along the lines of your advice about not moving anything further than a duck might fly. We’re still waiting for our bullrush to arrive! I was hoping to put in sticklebacks (I hadn’t worked out where from) but will now probably just wait. I would also be interested to here what sort of response you’re getting from ‘the big pond dip’. I’m looking forward to the results too as I enjoyed reading about your Bucks garden pond survey.
    In your recent post about tadpoles eating the moss in your pond, was it a special type of moss, and had it found its own way into the pond like your bullrush?
