Description:  Adults are wasp mimics with an abdomen that is narrowly joined to the thorax.   Most species have a bulbous head with a long proboscis.  They hover near flowers, feed on nectar, and lay their eggs on other visiting pollinators (mostly bees).   The larvae are internal parasitoids of their hosts.
