Food

"...90% of Torymus with known hosts are ectoparasitic upon gall-forming insects of the families Cecidomyiidae and Cynipidae. A few species are parasitic upon gall-forming Psyllidae, Eurytomidae, and Tephritidae. Single records are known of Torymus reared from eggs of Cicadidae (Nearctic) and larvae of Coleoptera, Lepidoptera, and Coccidae (Palearctic). T. varians and T. seminum are both phytophagous species, the former feeding in seeds of apple, pear, and hawthorn, and the latter in Acer seeds. T. aea and T. eurytomae have been shown to develop on the host larva as well as phytophagously in surrounding plant tissue. In almost every case known, members of Torymus feed upon host organisms concealed either in a gall or other protected plant tissue such as a stem, flower head, or fruiting body. The commonest plants upon which hosts of Torymus are found are Quercus (Fagaceae), Rosa (Rosaceae), and innumerable Compositae." (2)
