How Big Is a Queen Wasp?

According to National Geographic, wasps, and by extension their queens, can reach lengths of over 1.5 inches, although this is determined by species. The Asian giant hornet queen, for example, boasts a body length of nearly 2 inches.

Over 30,000 species of wasps exist. Close relatives of bees and ants, wasps can be divided into two categories: social or solitary. All species build nests, which is usually done by the queen after she has been fertilized the previous year. Wasp nests are built using pulp, which the queen wasp chews and mixes with her saliva. Social wasps can be extremely aggressive when threatened, emitting pheromones to attract other colony members.
