A wasp is a flying insect. There are more than 100,000 species of wasps and a lot of them have venomous stings. Unlike a bee, they do not die after they use their sting. Baby wasps or larvae eat other insects. Adult wasps hunt for food by stinging it and bringing it back to the nest for their baby wasps or larvae to consume. These adults also feed on nectar, pollen, fallen fruit, and other dead insects. Aggressive wasps will invade honey bee hives and steal honey or even drink the blood of honey bees. They also eat any sweet substance such as jam, cake, and other human food.
