Titan Beetle

The largest beetle by body length in the world. Adults do not feed, surviving on fat reserves from the larval stage. Their mandibles can snap a pencil in half.

💡

Did You Know?

The titan beetle larva has never been found in the wild — scientists only know adults. The larval boreholes in dead trees suggest larvae may grow up to 300 mm long.

Japanese Oakblue

A beautiful lycaenid butterfly with brilliant metallic blue upperwings and cryptic brown underwings. Found in oak forests where its larvae live in association with ants. Known as 'murasaki-shijimi.'

💡

Did You Know?

The caterpillars produce sweet secretions that attract ants, which then guard them from predators in a mutualistic relationship.
