Thread-waisted Wasp with its prey. These wasps sting and paralyze a caterpillar and then drag it into a burrow where its eggs have been laid. The eggs hatch and begin to feed on the caterpillar which is still alive. A grisly sort of business, but an effective way to provide fresh meat for their offspring. I watched this little drama for about twenty minutes as the wasp enlarged the hole to accommodate the size of the caterpillar, dragged it underground, and then backfilled the hole. The neat pile of excess dirt was four inches away.
