Hyphantrophaga virilis
Hyphantrophaga virilis is a tachinid fly (family Tachinidae) known to parasitize caterpillars of the California Oak Moth (Phryganidia californica). The species was described in 1924 and occurs in North America. Like other tachinid flies, it develops as an internal parasitoid, eventually killing its host. Records indicate it is one of several parasitoids associated with oak moth population dynamics along the California coast and in Oregon.
