    Tiphiidae: Brief Summary
    provided by wikipedia

    The Tiphiidae (also known as the tiphiid wasps) are a family of large solitary wasps whose larvae are parasitoids of various beetle larvae, especially those in the superfamily Scarabaeoidea. Until recently, this family contained several additional subfamilies, but multiple studies have independently confirmed that these comprise a separate lineage, and are now classified in the family Thynnidae.

    The females of some Brachycistidinae are wingless, and hunt ground-dwelling (fossorial) beetle larvae. The prey is paralysed with the female's sting and an egg is lain on it so the wasp larva has a ready supply of food. As some of the ground-dwelling scarab species attacked by tiphiids are pests, some of these wasps are considered beneficial as biological control agents.

    Brief Summary
    provided by Catalog of Hymenoptera in America North of Mexico
    So far as is known all of the North American taxa are parasites of larvae of fossorial species. In the primitive subfamily Tiphiinae, species of Tiphia F. have been reported as parasites of scarabaeid larvae. A few exotic species have been liberated in North America for control of economically important pest scarab species. Hosts of the other genera of Tiphiinae are unknown. In the Myzininae, species of Myzinum Latr. have scarabaeid larvae as hosts; it is anticipated that our native Pterombrus Sm. parasitize tiger beetle larvae as do some of the Neotropical species. Biology is unknown for the Anthoboscinae and Brachycistidinae, but the species probably have as hosts deserticolous scarabaeid larvae. The Methochinae parasitize tiger beetle larvae, and the Myrmosinae are parasites of ground-nesting aculeate Hymenoptera.
