Researchers have discovered that certain stink bug species use a cordycep-like fungus to defend against parasitic wasps.
Special glands on the legs of these stink bugs were initially mistaken for "ears" due to their unusual location.
Unlike crickets, moths, mantises, and cicadas, which use organs on their front legs, thoraxes, or abdomens to detect sound, these stink bugs do not have tympanal organs, or an auditory system.
For years, entomologists assumed that organs on certain stink bug legs must function in the same way.
A study published in the journal Science on October 16, conducted by biologists from multiple universities in Japan, reveals the complex and unique characteristics of these stink bugs.
The research focuses on the females of around 100 stink bug species known as Dinidoridae, shedding light on their unusual defense mechanism.
