A parasitic wasp that flew among dinosaurs had a Venus flytrap-like contraption on its abdomen that likely allowed it to inject eggs into insects it entrapped.

An extinct lineage of parasitic wasps dating from the mid-Cretaceous period and preserved in amber may have used their Venus flytrap-like abdomen to capture and immobilise their prey. Research, published in BMC

Modern-day parasitoids in the same superfamily—Chrysidoidea—include cuckoo wasps (which, as their name suggests, lay their eggs in the nests of their hosts) and bethylid wasps (which paralyze their prey before hiding the body and laying eggs into the poor victim.)
