Embolemidae is a small family of around 64 species and 3 genera distributed around the world.[1] They are small solitary parasitoid wasps, and are parasites on planthopper nymphs of the families Achilidae and Cixiidae.[2]


Females are wingless while males have wings, and in temperate regions emerge later than the females, which overwinter as adults.[3] The wingless females have been recorded from the nests of ants and small mammal burrows,[1] or under stones in pastures and grasslands and they appear to act as ant mimics. A Palearctic species, Embolemus ruddii, has been found in association with the ant species Formica fusca and Lasius flavus, while in Japan, Embolemus walkeri was taken in a nest of another ant, from the genus Myrmica.[4] A Nearctic species, Embolemus confusus, has been reared from nymphs of a planthopper in the family Achilidae, where the host fed on fungi beneath the bark of rotting logs. The wasp larva lives in a bulging sac attached to the host nymph between the second and third segments.[4][5]
