Dryinidae is a cosmopolitan family including 41 genera and almost 1500 species classified in eleven subfamilies, five subfamilies of which (Aphelopinae, Anteoninae, Bocchinae, Dryininae, and Gonatopodinae) also occur in the Czech Republic and Slovakia. The adults are small to medium-size, usually black or brown coloured insects, with 10-segmented antennae in both sexes and usually chelate fore tarsi (except Aphelopinae). Females are often brachypterous or apterous and ant-like in appearence and behaviour. The protarsus of both sexes is modified by an enlargment of one claw and a lateral expansion of the fifth tarsomere.  Adults are active from April to September, univoltine or bivoltine, overwintering in pupal or praepupal stage. Males live only a few days, do not feed or only on sugar solutions, females feed on sugar solutions and haemolymph and tissues of their hosts, grasping them with their chelae and making them wounds. The prey may die or survive, according to the severity of its wounds. Host-feeding is absent only in the non-chelate Aphelopinae. Dryinids are parasitoids of nymphs or adults of planthoppers (Fulgoromorpha) and leafhoppers (Cicadomorpha).

Altogether 38 species are known from the Czech Republic (33 from Bohemia, 34 from Moravia).

Family Embolemidae – vejřenkovití

Embolemidae are a widespread family, including three genera and 39 species. Adults are usually dull black or brown, sexually dimorphic with males always macropterous and females macropterous, brachypterous or apterous, with an unmodified protarsus. Little is known of their ontogeny and ecology, but a Nearctic species has been reared from nymphs of Achilidae (Fulgoromorpha) feeding on subcortical fungi with the larva developing in a similar manner to those of Dryinidae. In the Palaearctic region, brachypterous females occur in soil, ant nests, in burrows of small mammals, and also hibernate in these places. The adults are frequently observed in autumn and early spring after the hibernation. Only the species Embolemus ruddii Westwood, 1833 occurs also in the Czech Republic and Slovakia.
