These stink bugs use cordycep-like fungus to fend off parasitic wasps

Stink Bugs' Unique Defense Mechanism

Researchers have discovered that certain stink bugs utilize a cordycep-like fungus to defend against parasitic wasps.

Initially, special glands on the legs of these insects were mistaken for "ears". However, a recent study published in the journal Science reveals that these organs do not function as an auditory system.

Unlike crickets, moths, mantises, and cicadas, which use organs on their legs, thoraxes, or abdomens to detect sound, female Dinidoridae stink bugs do not possess tympanal organs.

The truth is more complex—and creepy.

A team of biologists from multiple universities in Japan collaborated on the study, which was published on October 16.
