Many life histories adapted to parasitizing hosts as diverse as aphids, bark beetles, and foliage-feeding caterpillars. Many species are egg-larval parasitoids, laying eggs within host eggs and then not developing until the host is in the larval stage. Unlike ichneumon wasps, many pupate in silken cocoons outside the body of the host and others spin cocoons entirely apart from the host.(4)
Also unlike ichneumonid wasps, very few braconids use host pupae to complete their life cycles, except for fly parasitoids in Alysiinae and Opiinae.
Examples of life cycles:
molecular evidence supports the monophyly of the cluster of subfamilies with cyclostome "mouth"(1)
defined by the dorsoventrally short clypeus and the concave labrum, bordered ventrally by the mandibles:
Some are used for pest control, especially in agriculture.
