I wonder whether artists were inspired by these creatures when they were creating an image of an alien for movies. Because now when I look at a mantis I see some kind of an alien from another planet. Found one such an alien today in my yard among the flowers. Mantises are masters of disguise, they are very much skilled in the art of masquerade, mimicking the exact shape of a leaf or hue of a petal. These insects camouflage themselves both to hide from predators such as birds and lizards, and to hunt successfully. There are 1800 types of mantis and their disguises are quite diverse - differing in colour, shape, and texture.
Doesn't it look like an alien?
