Explanation of Names
Trichopoda pennipes (Fabricius 1781)
Bright orange abdomen, velvety black head and thorax, and a fringe of short black hairs on the hind legs. Male: ferrugineous spot in the wing, abdomen dark orange at apex; female: wing evenly dusky, abdominal tip black.
Hosts: various pentatomorph bugs (Coreidae, Largidae, Pentatomidae, Scutelleridae); also recorded ex Tenodera australasiae
; Anasa tristis
is an important common host
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.
introduced into Europe during late 1980s and is now frequently spotted in the south(2)
