A Wasp (Vespula vulgaris) is any insect of the order Hymenoptera and suborder Apocrita that is not a bee or an ant. Less familiar, the suborder Symphyta includes the sawflies and wood wasps, which differ from the Apocrita by having a broad connection between the thorax and abdomen. There are several species of wasp and some of these measure up to 30 millimetres in length. There are two types of wasps: Social Wasps such as Common Wasps, Paper Wasps, Yellowjackets and Hornets.
