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.
Did You Know?
This beetle vectors the pine wood nematode (Bursaphelenchus xylophilus), which has killed millions of pine trees across Japan since the disease was first described in 1905.
Madagascar Tortoise Beetle
A rounded, dome-shaped beetle with transparent margins around the elytra that make it look like a tiny tortoise shell. The center of the shell often displays metallic gold or green coloration.
Did You Know?
The golden coloration fades after death, as it depends on a thin layer of moisture beneath the cuticle that dries out in preserved specimens.
