Introduction

This is a large subfamily that comprises small to large species. The defining feature of this group is the presence of a longitudinal row of stout spines on the fore tibia, a large head on often a slender, elongate body, and a cyclostome depression above the mandibles (see Braconinae).

The group is worldwide in distribution but for Australia most species are undescribed. Although only 26 species are so far recorded, a revision currently in progress indicates that the true size of the fauna is close to 400 species, and includes a greater proportion of reduced-winged species compared with other regions.

Doryctines are mostly ectoparasitoids of wood-boring coleopteran larva and consequently are commonly collected near fallen trees and rotting logs. A few species have also been reared from lepidopteran and sawfly larvae. Several Australian species are being used as biological control agents overseas against beetle pests of eucalypts.
