The answer to 'what is wasp' is that a wasp is a flying insect that belongs to the order Hymenoptera. Wasps are typically slender with a narrow waist, and they have two pairs of wings and a stinger. Wasps are known for their aggressive behavior and can sting humans if they feel threatened.
Wasps play an important role in the ecosystem, as they are predators that feed on other insects and help to control pest populations. Some species of wasps are also important pollinators, helping to transfer pollen from one plant to another. However, certain species of wasps, such as the yellow jacket, can be a nuisance to homeowners and can pose a risk of stinging if their nests are disturbed.
