The answer to 'what is wasp' is that wasps are flying insects that belong to the order Hymenoptera. They are closely related to bees and ants, but have distinct characteristics that set them apart. Wasps have slender bodies, narrow waists, and two pairs of wings. They come in a variety of colors, including black, yellow, white, and red, and range in size from small to large.
Wasps are known for their aggressive behavior and ability to sting, which they use to defend their nests and protect their young. They build their nests in a variety of locations, including under eaves, in tree cavities, and even inside the walls of homes. Wasps play an important role in the ecosystem, as they are predators of other insects and help to pollinate plants.
