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.
Rabbit Flea
A flea specific to European rabbits with a remarkable reproductive strategy tied to its host. It can transmit myxomatosis between rabbits.
Did You Know?
Rabbit flea reproduction is controlled by rabbit hormones — the flea can only breed when feeding on a pregnant doe near the time of birth.
