Found on flowers either mating, searching for caterpillars, or drinking nectar, female Thread-Waisted Wasps work hard to ensure the next generation gets a great start. She builds a burrow and fills it with fertilized eggs. She hunts and tackles a plump caterpillar and stings it, paralyzing, but not killing it. She then hauls the paralyzed caterpillar back to her burrow and places it next to her eggs. She then carefully covers the entrance of her burrow with dirt, debris and rocks to hide it from things that would eat her eggs and rob her of all her hard work. Once hatched, the wasp larvae feed on the still immobile caterpillar until they pupate. When they emerge as winged adults, the search for nectar to drink and a mate begins anew.
