Assassin bugs belong to the insect family Reduviidae. The larger species is capable of inflicting a painful bite and injecting a harmful defensive fluid if handled. They are medium to large bugs (1-2 cm in length) and have a narrow head with large eyes and a short, curved beak. They are often dull black or brown, with red or orange stripes or markings. The young (nymphs) resemble the adults but do not have wings.
