|Adult female Tenodera angustipennis|
Tenodera angustipennis is a species of mantis native to Asia and nearby areas of Oceania. The species was introduced and became established in the eastern United States. Tenodera angustipennis was noticed as early as 1921 in Aberdeen, Maryland, but that occurrence was not noted in a published record until 1933.
This species has two common names narrow-winged mantis and Japanese mantis in English. This insect is known as チョウセンカマキリ (translates to "Korean mantis") in the Japanese language and 참사마귀, (an alternative name which translates to "true mantis") as well as just plain 사마귀 (a formal name) in the Korean language (사마귀 can mean the whole order of Mantodea or this specific species of praying mantis).
Adults and nymphs
Size: Males 65~80 mm, females 68~85 mm in length. Tenodera angustipennis are often brown or green. Tenodera angustipennis proportionately have a more elongate pronotum and shorter, narrower tegmina and wings than Tenodera sinensis. T. angustipennis have a brown, patterned streak on each of their transparent hind wings, while T. sinensis have hind wings that are completely patterned and brown.  The Chinese mantis is thicker or more stocky than the narrow-winged, mantis. It can be easy for a person to tell apart between the adults of these two species, Tenodera angustipennis and Tenodera sinensis when the two species are placed side by side.
The oothecae of Tenodera angustipennis are elongate, about 40 to 60 millimeters long and about 14 millimeters in diameter and are sometimes mistaken to be Stagmomantis carolina oothecae. T. angustipennis oothecae probably hatch around 1 to 2 weeks later than T. sinensis do.
This species occurs in China, Hawaii, India, Java, Korean Peninsula, Ulleung-do, Jejudo, Taiwan, Vietnam, Honshu, Shikoku, Kyushu, Tsushima Island, Okinawa Island.
Non-native range in the United States:
Delaware, Maryland,New York, North Carolina, New Jersey, Ohio, Pennsylvania,Virginia.
The oothecae are often laid on twigs of shrubs, stems of tall herbs, but in field margins they seem to prefer to lay their oothecae on tree trunks and fence posts. In some areas T. angustipennis is just as common as T. sinensis.

-  Bugguide.net By Bugguide user Paul Krombholz. Title: Tenodera angustipennis, mating pair. Location: New Jersey, USA. The person's description about this Bugguide photo: "These are lab-reared mantids, but their ancestors were collected in New Jersey, near Princeton University in a field where both T. sinensis and T. angustipennis existed. How do you tell them apart? The differences are subtle. Angustipennis is a bit more slender than sinensis, the green borders of the wings are narrower, The colors are slightly different in both green and brown forms. Sinensis green is a little bluer and sinensis brown is darker and a little more yellow. Angustipennis has an orange spot bordered in black between the forelegs (used in threat display), and sinensis has yellow, instead of orange. The egg cases are very different, that of sinensis being large and puffy, and that of angustipennis being flattend with very little foam material."
