Arichanna gaschkevitchii

Arichanna gaschkevitchii (or hyoumonedashaku (ヒョウモンエダシャク) in Japanese) is a species of geometrid moth native to Japan and commonly found throughout the country. The adult's wingspan can reach a length of 40 - 50 mm. This moth will store large amounts of grayanotoxins from the larval host plant in the body tissue to deter predators. The species was first described by Victor Motschulsky in 1860.
