Banded Hairstreak

A small dark brown butterfly with conspicuous bands of white-edged dark dashes on its hindwing underside. It has a short thin tail and a small orange spot near the tail.

💡

Did You Know?

It rubs its hindwings together after landing, moving the tails to mimic antennae and trick predators into attacking the wrong end.

Japanese Lunar Moth

A beautiful pale green moon moth found in Japan, known as 'o-mizuao.' Features long, elegant tail streamers on the hindwings. Closely related to the Luna moth of North America.

💡

Did You Know?

The long tail streamers on the hindwings create acoustic interference that confuses bat echolocation, helping the moth evade predation.
