Larvae are parasitoids of white grubs (scarab larvae), especially Phyllophaga(2) and other Scarabaeidae, and to a lesser extent Cicindelinae. Adults take nectar, mostly from Asteraceae and Apiaceae
Life Cycle
Female lays one egg per grub in soil. Larva hatches, penetrates host, first feeding on non-essential tissues, later feeding on essential organs and killng host. Pupae overwinter in soil; adults emerge in early summer. One generation per year.(2) Adult males often congregate on vegetation.
Used in turfgrass pest management
