Japanese Rhinoceros Beetle (Blue)
The northern Japanese subspecies of the rhinoceros beetle, found in Hokkaido. Slightly smaller and darker than mainland populations, adapted to cooler climates with a shorter active season.
Did You Know?
Hokkaido rhinoceros beetles emerge later in summer than their southern relatives and have a compressed breeding season due to the shorter northern summer.
Click Beetle
Has a special mechanism that allows it to snap its body with a click, launching itself up to 30 cm into the air. The large eyespots on its thorax startle predators.
Did You Know?
Click beetles launch themselves into the air without using their legs — they use a peg-and-groove mechanism on their thorax that releases like a spring, reaching accelerations of 400g.
