Io Moth
Named after Io from Greek mythology. Hindwings display large eyespots that flash open to startle predators. Caterpillars are covered in urticating spines that cause a painful sting.
Did You Know?
When threatened, the Io moth suddenly flashes open its hindwings to reveal two enormous eyespots — the sudden appearance of "eyes" startles predators into backing off.
Atlas Moth
One of the largest moths in the world by wing area. Adults have no mouths and do not eat, living only 1-2 weeks on stored fat. Wing tips mimic snake heads.
Did You Know?
The atlas moth has no mouth — as an adult, it cannot eat. It survives entirely on fat stored during its caterpillar stage, living just long enough to mate.
