Eulophidae is a large family of Hymenopteran insects, with over 4,300 described species in some 300 genera (see List of Eulophid genera). These minute insects are challenging to study as they deteriorate rapidly after death unless extreme care is taken (e.g., preservation in ethanol), making identification of most museum specimens difficult. The larvae of a very few species feed on plants but the majority are primary parasitoids on a huge range of arthropods at all stages of development. Eulophids are found throughout the world in virtually all habitats (one is even aquatic, parasitising psephenid beetles).

Most species are separable from other Chalcidoidea by the possession of only 4 tarsomeres on each leg, and by a reduced number of flagellomeres compared to other families. Chalcidoidea is a superfamily of Hymenoptera There are nineteen families Agaonidae Walker, 1846 Aphelinidae Thomson, 1876 Chalcididae Latreille, 1817 Encyrtidae Walker, 1837 Eucharitidae Latreille, 1809 Eulophidae (including Elasmidae) Westwood, 1829 Eupelmidae Walker, 1833 Eurytomidae Walker, 1832 Leucospidae Fabricius, 1775 Mymaridae Haliday, 1833 Ormyridae Forster, 1856 Perilampidae Latreille, 1809 Pteromalidae Dalman...
