Japanese Pine Sawyer
A large longhorn beetle known as 'matsu-no-madara-kamikiri,' responsible for transmitting pine wilt disease in Japan. The larvae develop in pine wood, and adults carry the devastating pine wood nematode.

Habu's Ground Beetle
A large Japanese ground beetle with deeply sculptured elytra and striking blue-violet metallic coloring. It is widespread in lowland forests across western Japan.
Did You Know?
Japanese Carabus beetles have been intensively studied for decades, making Japan one of the best-documented regions in the world for ground beetle ecology and evolution.
