Hymenopus is a genus of flower mantises belonging to the family Hymenopodidae. This genus is widespread in the tropical rain forests of East Asia.
Flower mantises are those species of praying mantis that mimic flowers. Their coloration is an example of aggressive mimicry, a form of camouflage in which a predator's colors and patterns lure prey. Most species of flower mantis are in the family Hymenopodidae. Their behavior varies, but typically involves climbing a plant until they reach a suitable flower, and then staying still until a prey insect comes within range. Many of these mantises have deimatic displays to startle or put off potential predators. Deimatic behavior, threat display, or startle display in animals means any pattern of behavior, such as suddenly displaying conspicuous eyespots, to scare off or momentarily distract a predator, thus giving the prey animal an opportunity to escape. The term deimatic or dymantic originates from the Greek δειματόω (deimatόo), meaning "to frighten".
Many species of flower mantis are popular as pets.
