Instead of butterflies - how about red ants - there are lots in my garden. How do you hunt red ants?

Incidentally, I once saw a red ant funeral. In the house I used to live, the garden was absolutely plagued with them and, I confess, I had gone round with the white powder, to try and stem the flow a bit.   

Not long afterwards. I saw the 'survivors' of one nest, having a clear out of their dead. They were carrying them all out of the nest and chucking them in my pond!

And once, when in Rome, I saw a train of caterpillars, but that's another story...
