The Chinese mantis (Tenodera sinensis) is a species of praying mantis native to Asia and the nearby islands. In 1896 this species was accidentally introduced by a nurseryman at Mt. Airy near Philadelphia, PA. Tenodera sinensis often is erroneously referred to as Tenodera aridifolia sinensis because it was at first described as a subspecies of Tenodera aridifolia, but Tenodera sinensis is now established as a full species.
