I have found the most interesting things when checking for bugs; for instance, a lovely green caterpillar in the broccoli, teeny bugs in strawberries that looked like the little greenish seeds on the outside of the strawberry, and most lovely of all, a slug in homegrown lettuce. I kept it for a pet in a herring jar covered with the net bag from onions to keep it from climbing out for about three weeks until unfortunately it dried out.
