Japanese Diving Beetle
A large diving beetle native to Japan, once common but now increasingly rare. It has suffered severe declines due to habitat loss and invasive species.
Did You Know?
The American bullfrog, introduced to Japan, is a major predator of this beetle and a key driver of its decline.
Small-eyed Sphinx Moth
A pinkish-brown sphinx moth whose hindwings bear a small blue eyespot ringed in black and yellow. It relies on camouflage at rest but flashes the eyespot when threatened.
Did You Know?
The species name 'myops' means 'short-sighted,' a reference to its notably small hindwing eyespot.
