Stink Bugs' Unique Defense Mechanism
Researchers have discovered that certain stink bugs utilize a cordycep-like fungus to protect themselves against parasitic wasps.
Initially, special glands on the legs of these insects were mistaken for "ears" due to their unusual location. However, a study published in the journal Science on October 16 reveals that these organs do not function as auditory systems.
Unlike crickets, moths, mantises, and cicadas, which use organs on their legs, thoraxes, or abdomens to detect sound, female Dinidoridae stink bugs lack tympanal organs, the insect equivalent of an auditory system.
For many insects, their “ears” aren’t located anywhere near their heads.
- Crickets have evolved organs on their front legs to detect sound.
- Moths, mantises, and cicadas use similar appendages on their thoraxes or abdomens to gather auditory information.
