Life Cycle
Female lays one to several eggs on a host. The hatched larvae burrow into the bug's body, though only one larva per host will survive. Eventually a cream-colored maggot exits the host (which soon dies) and pupates in a dark puparium in the soil; adult emerges ~2 weeks later. There are up to 3 generations a year depending on location; larvae may overwinter inside overwintering hosts. See Worthley (1924)
Used to control of heteropteran pests; may hover above squash plants in search of prey.
According to Paul Beuk, has been "introduced into Europe and is now frequently spotted in the south. Its exotic appearance has dumbfounded many a European entomologist."
