Ha. I've some HUGE woodlice in the garden at the moment. Big bastards, they are. The ones that curl up, though, are usually called pillbugs.
Earlier in the year I watched a butterfly chasing a bumblebee across a meadow for at least 15 minutes. Persistent little thing, it kept on the tail of that bee, round and round, up and down. I thought at first it was attracted by the smell of pollen but, when I read that butterflies are mainly influenced by colour, I decided that it's principal purpose in the chase must be sodomy.
