Tenodera sinensis The Chinese mantis 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. The ooth (egg Case) hatches up to 200 nymphs.
Ooth can take 3-12 weeks to hatch. Much can go wrong and we cannot guarantee to hatch. I can tell you that the ooth we send is fertile and picked by an expert who knows.
The Chinese mantis is a long, slender, brown, and green praying mantis. It is typically longer than other praying mantises species reaching just over 11 centimeters, 4.3" 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 andTenodera angustipennis are similar in appearance, however, you can tell them apart by locating a spot in between their front legs. If it is yellow then it is a Chinese mantis but if it is orange then it is a narrow-winged mantis. The female can produce several semi-spherical oothecae, roughly 2 cm. in diameter, containing up to 400 eggs. The oothecae are often affixed to vegetation such as bushes and small trees.
