The Malaysian orchid mantis Hymenopus coronatus mimics a flower both in body shape and coloration. Historically, it has been assumed that the orchid mantis resembles a flower and uses crypsis to hide from unsuspecting prey and predators. I have seen photographs of flower mantids blending into flowers so well they are difficult to spot. A study by O’Hanlon and colleagues* however found that the resemblance to flowers is not always used to hide among flowers. The mantid often rests on foliage and feeds on pollinators that mistake the mantid for a flower. The color of the mantid is similar to the color of common flowers. The mantid can attract more prey when it is not near a flower.
