Sirenobethylus

Sirenobethylus charybdis is an extinct species of wasp. It had a unique anatomical feature on its abdomen that may have acted as a grasping device.

Discovery

The fossil of Sirenobethylus charybdis was discovered in a piece of amber from the Kachin State of northern Myanmar, dated to around 99 million years ago during the mid-Cretaceous period. The specimen was preserved in remarkable detail, allowing scientists to examine its distinctive abdominal appendages, which resembled the snap-trap mechanism of a Venus flytrap. Researchers suggested these features may have been used to grasp or immobilize prey during parasitism, similar to behaviors seen in some modern wasps.
