Emerald Jewel Wasp

This was one tough little dude to photograph live. They move franticly without ceasing. Members of the largest subfamily, Chrysidinae, are the most familiar; they are generally kleptoparasites, laying their eggs in host nests, where their larvae consume the host egg or larva while it is still young, then the food provided by the host for its own juvenile. Chrysidines are distinguished from the members of other subfamilies in that most have flattened or concave lower abdomens and can curl into a defensive ball when attacked by a potential host, in the manner of a pill bug.
