Appearance:
The wasp has a chewing-sucking mouthparts and antennae with 12 or 13 segments. Usually winged, the thorax and abdomen are connected by a slender 'waist'. Females have a formidable sting.
Adults feed mainly on nectar, but larvae feed on insects provided by the mother. More than 20,000 species are known, the vast majority of which are solitary, and social wasps are limited to about 1,000 species of the wasp superfamily Vespoidea (hornets) Vespidae (wasps), which also includes the large hornets and small yellow-coated hornet species.
These species differ from the Pompilidae species and other wasps in that their wings are folded longitudinally when at rest.
The adult wasp has the standard physical appearance of an insect, including a head, thorax, abdomen, three pairs of legs, and a pair of antennae; it also has a single eye, compound eyes, and wings, which are characteristic of most insects***; and a degraded oviduct, or venomous needle, hidden in the caudal end of the abdomen.
The adult body is mostly black, yellow and brown, or a single color. The body is smooth or with engraved points of different sizes. The velum is generally short. Feet are long. The wings are developed and fly rapidly. At rest, the forewings are folded longitudinally and cover the back of the body.
