Buresiinae Eurytominae Heimbrinae Rileyinae The Eurytomidae are a family within the superfamily Chalcidoidea.

Unlike most chalcidoids, the larvae of many are phytophagous (feeding in stems, seeds, or galls), while others are more typical parasitoids, though even then the hosts are usually found within plant tissues.

Some species of eurytomids are unusual in the sense that they are parasitoids of spider eggs.

They tend to be dull and not metallic, and heavily punctured, with very thick, collar-like pronota.

As of 2021[update], Eurytomid genera include:[2] Buresiinae Lotfalizadeh et al., 2007[3] Eurytominae Walker, 1832 Heimbrinae Burks, 1971 Rileyinae Ashmead, 1904
