The Chinese mantis (Tenoera aridifolia sinensis) is a species of praying mantis. Originating from China, they were first introduced to North America around 1895 as a source of pest control. Since then, the species has spread throughout much of southern New England, and the Northeast United States. The Chinese mantis looks like a long and slender praying mantis, with different shades of brown. The adult has a green lateral line down its wing. It is typically larger than most other mantises, growing up to 10 cm (4 inches) in length, and are the largest mantis species in North America.
