what is the smell of a stink bug
Brown marmorated stink bug The odor from the stink bug is due to trans-2-decenal and trans-2-Octenal.[13] The smell has been characterized as a "pungent odor that smells like coriander."[5] The stink bug's ability to emit an odor through holes in its abdomen is a defense mechanism meant to prevent it from being eaten by birds and lizards. However, simply handling the bug, injuring it, or attempting to move it can trigger it to release the odor.
