An insect belonging to the order Hemiptera and the family Pentatomidae. This is the only species known from the Pentatomidae family in Japan. It is distributed in Honshu, Shikoku, Kyushu, Okinawa, the Korean Peninsula, and China, and mainly lives on flat land. Body length is 14 to 18 mm. The body is light yellowish brown. The head is triangular. Both the proboscis and antennae are short. It parasitizes Japanese silver grass and moves around the leaves rather inactively. In May and June, it lays around 14 eggs in two rows on the undersides of leaves. The larvae have a distinctive flat body shape. They emerge around August and overwinter as adults.
