Order Coleoptera, family Brachinidae. When it encounters an enemy or threatens it, it emits a pale yellowish-white gas from the tip of its abdomen with a buzzing sound, and is also called the Heppirimushi. Body length 11-18mm. The head and pronotum are wrinkled and covered with large dots. The elytra have shallow, thin grooves, and the intercostal space has a thick ridge in the center. The yellowish-brown pattern on the elytra is conspicuous. It is distributed from Hokkaido to Amami Oshima, and can be found under damp dead grass. If the gas hits the skin directly, it causes a type of burn. Another species, P. javanus, lives in the Okinawa region.
