Vengeance is mine. Well, really I had nothing to do with it… but the tobacco hornworms that have eaten all my tomato plants are now themselves “meals on wheels” for the parasitic braconid wasp. The wasp laid its eggs just under the skin of the caterpillar. They’ve spent their larval stage eating the worm from the inside out, but not killing it. They’ve now burrowed back OUT of the wasp, and pupated into tiny cocoons, still living off their zombie host. Soon, the little adult wasps (about 1/8″ long) will emerge and the caterpillar will die.
