Lepidoptera larvae, mainly Lymantriidae and Lasiocampidae. It attacks Gypsy Moth (Lymantria dispar) and Lymantria monacha L. Used as biocontrol
A European species introduced into New England and now widespread in Canada as well. The key to central European Tachinidae lists habitat, habits, and hosts: "Open countryside, thin deciduous woodland, orchards, Pine forest. Mid May to End September, especially End July to Early September, at least 2 generations. Usually on flowers; not rare, easier to rear from the host than to catch in open areas. Numerous Lymantriidae, Lasiocampidae, Noctuidae, Arctiidae and Zygaenidae, rare on Sphingidae, Nymphalidae, Pieridae, Notodontidae, Geometridae and Endromididae."(1)
