If you hate cockroaches, you should love the ensign wasp. It has a strange, almost triangular abdomen that bobs up and down at the end of a long waist. It’s a specialized cockroach parasite, laying eggs in cockroach egg cases. The wasp larvae live inside the egg case and eat all the cockroach eggs. The species we have on St. Martin is found all around the world, being introduced along with the cockroaches it feeds on.
