Wasp
Apocrita See text for explanation.
A wasp is a predatory, flying, stinging insect, with a stinger and membranous forewings and hindwings. It is related to ants and bees, with all of them being members of order Hymenoptera, but is separated from ants and bees by having a stinger and no hair; bees have hair. A rough definition of the term wasp is any member of the aculeate family Vespidae. Almost every pest insect species has at least one wasp species that preys upon it, making wasps critically important in natural control of their numbers, or natural biocontrol. Parasitic wasps are increasingly used in agricultural pest control as they prey mostly on pest insects and have little impact on crops.
