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.
