What defense mechanism is used by the Yellow Crazy Ant instead of a prominent stinger found in Solenopsis invicta?
Answer
Reflex bleeding, releasing a foul-smelling chemical
When comparing the defense strategies of *A. gracilipes* to other common invasive pests, such as fire ants (*Solenopsis invicta*), a key difference emerges regarding stinging capability. The Yellow Crazy Ant workers do not possess a prominent stinger used for injecting venom. Instead, their primary physiological defense mechanism involves reflex bleeding. When disturbed or threatened, they release a chemical substance from their abdomen that is distinctively foul-smelling. This chemical emission serves as a deterrent, contrasting sharply with the stinging action employed by species like the fire ant.
