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.
Trilobite Beetle
Females are large, larviform, and look strikingly like trilobites from the Paleozoic era. Males are tiny conventional-looking beetles. One of the most extreme sexual dimorphisms in insects.
Did You Know?
Females of this beetle retain their larval form throughout life and look like extinct trilobites — males are tiny normal beetles, creating one of natures most extreme sex differences.
