In some species, the larvae are predatory themselves; the wasp eggs are deposited in clusters of eggs laid by other insects, and these are then consumed by the developing wasp larvae. [10] The largest social wasp is the Asian giant hornet, at up to 5 centimetres (2.0 in) in length. [11]
Of the wasp's 7,400 neurons, 4,600 are located in the brain. A small insect from other families often deals with the issue of having a large brain in relation to its head size by shifting its brain into its thorax and even abdomen. However, wasps cannot, as to keep their heads flexible, the head's connection to the thorax is relatively limited. [2]

Electron micrograph of antenna surface detail of a wasp (Vespula vulgaris) The three basic segments of the typical insect antenna are the scape or scapus (base), the pedicel or pedicellus (stem), and finally the flagellum , which often comprises many units known as flagellomeres . [ 10 ]
Musculature of ant mandibles Wasp drinking; the yellow mandibles can be seen on either side of the mouthparts. Most adult Hymenoptera have mandibles that follow the general form, as in grasshoppers. The mandibles are used to clip pieces of vegetation, gather wood fibers, dig nests, or to capture and disassemble prey.
The wasps, bees, and ants together make up the suborder (and clade) Apocrita, characterized by a constriction between the first and second abdominal segments called a wasp-waist , also involving the fusion of the first abdominal segment to the thorax. Also, the larvae of all Apocrita lack legs, prolegs, or ocelli.
Air enters the respiratory systems of insects through a series of external openings called spiracles. These external openings, which act as muscular valves in some insects, lead to the internal respiratory system, a densely networked array of tubes called tracheae. This network of transverse and longitudinal tracheae equalizes pressure ...
Vespula vulgaris, known as the common wasp, is a species found in regions that include the United Kingdom, Ireland, Germany, India, China, New Zealand [1] and Australia. It is sometimes known in English as the European wasp , but the same name is used for the species Vespula germanica or German wasp.
