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.
Big-headed Tiger Beetle
A nocturnal tiger beetle with a disproportionately large head and long curved mandibles. It is dark brown to black and hunts on sandy riverbanks after dark.
Did You Know?
Unlike most tiger beetles that hunt by day, this species is strictly nocturnal and is attracted to artificial lights near sandy habitats.
