Pelecinidae is a family of parasitic wasps in the
superfamily Proctotrupoidea. It contains only one living genus, ''
Pelecinus'', with three species known from the Americas. The earliest fossil species are known from the
Jurassic
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of ...

Members of ''Pelecinus'' are parasitic on larval beetles, flies,
green lacewings
Green lacewings are insects in the large family Chrysopidae of the order Neuroptera. There are about 85 genera and (differing between sources) 1,300–2,000 species in this widespread group. Members of the genera ''Chrysopa'' and ''Chrysoperla'' ...
