# Chinese mantis

The Chinese mantis (Tenodera sinensis) is a species of mantis native to Asia and the nearby islands. In 1896, this species was accidentally introduced by a nursery tender at Mt. Airy near Philadelphia, United States. 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.
Tenodera sinensis feeds primarily on other insects, though adult females sometimes catch small vertebrates. For example, they have been observed feeding on hornets, spiders, grasshoppers, katydids, small reptiles, amphibians, and even hummingbirds. Like most mantids, they are known to be cannibalistic. One study found that cannibalism occurs in up to 50% of matings. These mantids have been observed eating the larvae of monarch butterflies, while discarding the entrails.

## Description

The Chinese mantis is a long, slender, brown and green praying mantis. It is typically longer than other praying mantis species, reaching just over 11 cm (4.3 in), and is the largest mantis species in North America (spread throughout the Northeast United States). Its color can vary from overall green to brown with a green lateral stripe on the borders of the front wings in the brown color form. In low light, the eyes of the mantis appear black, but in daylight appear to be clear, matching the color of the head. Chinese mantids look similar to another mantis species that has been introduced to the United States, the narrow-winged mantid (Tenodera angustipennis). Tenodera sinensis and Tenodera angustipennis are similar in appearance; however, it is possible to tell them apart by locating a spot in between their front legs, as the spot is yellow in the Chinese mantis but orange in the narrow-winged mantis. The female can produce several semi-spherical oothecae, roughly 2 cm (0.8 in) in diameter, containing up to 300 eggs. The oothecae are often affixed to vegetation such as bushes and small trees.

## Native range

This mantis is native to China, Japan, the Korean Peninsula, Micronesia, and Thailand. Populations of T. sinensis in Japan are sympatric with Tenodera aridifolia, the Japanese giant mantis, of which T. sinensis was formerly considered a subspecies.

### Invasive status

The Chinese mantis is regarded by some experts as invasive in various regions of the United States, particularly where the native Carolina mantis (Stagmomantis carolina) is found. While commonly sold for pest control, it is said that Chinese mantids lack effectiveness in pest management. As ambush predators, they attack anything within reach that they can subdue, but they do not actively hunt for insect pests. Their non-selective predatory behavior and significant size has led to documented attacks on beneficial insects such as pollinators, small birds, mammals, frogs, and snakes. As a result, the Chinese mantis can alter food webs and affect the dynamics of local insect populations.

## Growth

Chinese mantises hatch in the spring, eat, grow, and molt through the summer, and lay eggs at the end of summer. When it gets too cold, they die, only living around a year long. First instar nymphs that eat less take a longer time to molt to the next instar and are smaller at the second instar than first instar nymphs that have been fed more.

## Captivity

Tenodera sinensis is a common pet for mantis enthusiasts, and oothecae can be purchased from plant nurseries across the US.

## Predators

The Chinese mantis is preyed on by other mantises, birds, and the Asian giant hornet in its native range. The female mantis specifically preys on male mantises. She often kills and eats her male partner after mating, providing nutrition for her offspring. Sexual cannibalism is a strange phenomenon not yet completely understood by scientists.

## Similar species

The European mantis (Mantis religiosa) and the Carolina mantis (Stagmomantis carolina) are both smaller mantises closely resembling the Chinese mantis. The European mantis is anywhere from tan to green in color and about 7.5 cm (3 in) long. The Carolina mantis, on the other hand, is only 6 cm (2.5 in) in length and varies more in color.

## Culture

There are two martial arts styles created to mimic the movements of the Chinese mantis. Developed in the Shandong province of China in the mid-17th century, Praying Mantis kung-fu is based on the quick movements and techniques of the Chinese mantis. An unrelated style of kung fu that was developed by the Hakka people in Southern China is known as Southern Praying Mantis.
Master Mantis, one of the supporting characters in the 2008 Dreamworks Animation film franchise Kung Fu Panda, is a Chinese mantis and one of the members of the Furious Five.
