Do Praying Mantis Eat Plants?
Praying Mantis will only eat meat and won’t consume any plants. However, they supplement their diet with pollen and the bees and flies that are attracted by it. Flowers, grass, and leaves of plants are camouflage for praying mantis, not food.
Praying Mantis are quite beneficial to a garden. Even in their early life stages, they will eat many pests from gardens such as caterpillars, leafhoppers, aphids, and small flies. As they grow, they’ll eat other pests and most animals and insects that are unfortunate enough to get close to it, such as moths, houseflies, mosquitoes, crickets, bees, grasshoppers, spiders, frogs, wasps, and even small birds.
During periods where food is scarce for praying mantis, they will eat pollen for as long as needed but will always prefer live pray when the option is available. Having these super-predators in a garden is not only beneficial, but they will also kill beneficial insects such as bees, butterflies, and moths. Having many praying mantis may not directly harm plants, but they will eventually hunt enough that necessary insects in the environment will become scarce.
