🧬 What is a "Caterpillar Tongue"?
The Scientific Truth: It's called an Osmeterium. It is a fleshy,
forked organ found in the prothoracic segment of caterpillars of the Swallowtail butterfly family.
Defense Mechanism
When threatened, the caterpillar everts (pops out) this organ. It looks like
a snake's tongue!
Chemical Weapon
It emits a foul-smelling secretion containing terpenes to repel predators
like ants and spiders.
Snake Mimicry
Combined with eye-spots on their body, the osmeterium helps the caterpillar
look like a dangerous snake head. 🐍
