A wasp is a flying insect that belongs to the order Hymenoptera, which also includes bees and ants. They have slender bodies with long legs and antennae, and their wings are usually clear or partly colored. Wasp species vary in size from small (about 1/4 inch) to large (up to 2 inches).
Wasps play important roles in ecosystems as they help control insect populations by preying on them for food. Some wasp species also pollinate plants, which is essential for plant reproduction and the production of fruits and vegetables. However, some wasps can be aggressive and sting humans or animals if they feel threatened.
Overall, "wasp" refers to a group of insects that are characterized by their slender bodies, wings, legs, and antennae, and play important roles in ecosystems as predators and pollinators.
