Life Cycle
Life history of T. pennipes and T. plumipes in Swan & Papp(3).
Mating may occur near nectar sources (P. Coin, pers. observation). Females hover over plants that attract their hosts (e.g., squash). Eggs are typically laid on underside of host. Only one larva per host will survive, though more than one egg may be laid on a given host. Newly hatched maggot bores into body of host and feeds on host's fluids for about two weeks. Eventually, it grows to almost the size of the host's body cavity. Maggot emerges at III instar, killing the host, and pupates in soil. Adult emerges in ~2 weeks. Second instar larva overwinters in the host's body.
Remarks
T. pennipes has been used to control of stink and squash bugs
