Bizarre Parasitoid Wasp Species Found Preserved in Kachin Amber

In a paper published in the journal BMC Biology, paleontologists described an extinct species of koinobiont parasitoid wasp found in mid-Cretaceous amber from the Kachin region of Myanmar. Named Sirenobethylus charybdis, this species may have used its Venus flytrap-like abdomen to capture and immobilize its prey.
