Mantises are exclusively predatory. Insects form the primary diet, but larger species have been known to prey on small lizards, frogs, birds, snakes, fish, and even rodents. they will prey upon any species small enough to successfully capture and devour.
Most species of mantis are known to engage in cannibalism. The majority of mantises are ambush predators, waiting for prey to stray too near. The mantis then lashes out at remarkable speed. Some ground and bark species, however, pursue their prey rather quickly. Prey items are caught and held securely with grasping, spiked forelegs.
Sexual cannibalism is common among mantises in captivity, and under some circumstances may also be observed in the field. The female may start feeding by biting off the male’s head (as they do with regular prey), and if mating had begun, the male’s movements may become even more vigorous in its delivery of sperm.
