Insects are known for having diets that are rich in plant matter such as flowers, seeds, nectar or leaves, but about one-third of all insect species are carnivorous, which means that they eat animal flesh. Although some carnivorous insects eat dung or rotting meat, the majority of them hunt for their food. For instance, beetles are predators that actively hunt for prey, such as slugs and worms. The beetles then use their sharp mouth appendages known as mandibles to trap, crush and eat their prey. Other carnivorous insects — notably mosquitoes — survive primarily on a diet that involves sucking the blood of humans or other animals.
