The eastern amberwing (''Perithemis tenera'') is a species of dragonfly in the family Libellulidae. It is very small, reaching a total length of no more than 25 mm. The males have orange or amber wings. Both genders have a red pterostigma. The eastern amberwing dragonfly is one of the only types of dragonfly that actively mimics a wasp. The yellow and brown stripes on its abdomen encourage predators to stay away. When perched, they will wiggle their abdomen and wings in a wasp-like fashion to deter other animals from eating it. Males have an elaborate courtship ritual. When a female approaches his territory, the male will lead her to his selected egg-laying site and hover above it with wings whirring and abdomen raised. The common name refers to its eastern range, although this dragonfly does extend westward well into the central part of the United States. The scientific name, ''tenera'', means delicate and alludes to its small size. ==Gallery== Image:Eastern Amberwing male.jpg|Male 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eastern amberwing」の詳細全文を読む スポンサード リンク
