The Eurytomidae contains species which exhibit a wide range of biologies, but the majority seem to be endophytic, either as phytophages or as parasitoids of phytophagous insects. There are two large groups of phytophagous eurytomids in Britain, those that develop on endosperm in seeds, and those that feed in plant stems, especially stems of grasses. The seed-feeding group is represented by two taxa, Systole, species of which feed in the seeds of Umbelliferae (Claridge, 1959b), and Bruchophagus, many species of which develop in the seeds of Leguminosae. The stem-mining group is represented in Britain by the large genus Tetramesa. Claridge (1961b) reviewed the biology of a number of British species. Several develop in the central cavity of grass stems, feeding above the nodes.
Many British torymids oviposit through plant tissue, usually into galls or developing seeds, but some oviposit into pupae concealed in silk or plant tissue. Torymid larvae may be entomophagous or, less commonly, phytophagous; some may even be both, feeding in turn on gall maker and gall tissue as in some Eurytomidae. 98 Eurytomidae are recorded in Britian and Irleand, but only two species are recorded as parasitodis of miners.

of the parasitoids and their associated host miners listed here
occur in Britain (albeit in quaratine or glasshouses only). The
associations themselves, however, may not be British.
