The ordo Mantodea is made up of more than 2,300 species of mantis. Their body size is around 3-7 cm. They have triangular heads, large compound eyes, and exible necks. Mantises are the only insects that can turn their heads around, so they can look the area behind them.Mantises defend themselves in many different ways. The head, thorax, and abdomen of the leaf mantis mimic the appearance of a leaf. This helps camouflage or disguise the insect. The dead leaf mantis startles predators by raising its front legs and lifting its wings when it is threatened. This reveals bright markings on its underside. All mantises have the same resting pose. They hold their front legs up and together, as if in prayer. The forward-facing eyes of this species help the mantis judge the distance to its prey accurately before it attacks.Adapted from: Nn, Pocket Genius Bugs Facts at your Fingertips, New York, Penguin Random House LLC, 2016.
