Preserved in amber, the wasp appears to have used a Venus flytrap-like structure on its body to grasp potential hosts.

For example, a group of wasps known as cuckoo wasps lay their eggs in the nest of another wasp species, and the larvae feast on their new hosts’ young once they hatch. A fossil enthusiast purchased ...

Bizarre parasitic wasps preserved in amber about 99 million years ago had trap-like abdomens that they may have used to ...

Meet Sirenobethylus charybdis, a wasp that the team half-jokingly called a ‘Cretaceous flytrap’ for its rear being shaped ...

charybdis indicates the wasps were parasitoids—insects whose larvae live as parasites and eventually kill their hosts. Modern-day parasitoids of the superfamily Chrysidoidea include cuckoo wasps ...

An extinct species of parasitic wasp dating back nearly 99 million years was found preserved in amber, according to researchers.

While some modern parasitoid wasps exhibit similar behaviors—like cuckoo wasps, which lay their eggs in other wasps’ nests—the flytrap-like structure of Sirenobethylus charybdis makes it ...
