Wasps often lay their eggs just inside the eggs of butterflies. The wasp larva (baby wasps) are able to get lots of nutrients and protection from the butterfly/caterpillar egg while its developing. After the caterpillar is born, the wasps continue lurking in the flesh of the caterpillar, soaking up more nutrients and drinking its blood. The wasp larva must keep its host alive, so it avoids damaging the vital organs.
