==Description== The adult wasp can measure from 0.9 to 5.0 mm in length and in some cases can reach 13 mm. The body of the adult wasp has a 'waist' where it is constricted in the middle. The rear legs have spurs which may be used for grooming. The antennae have 10 segments. Many species have a marked sexual dimorphism, where males are totally different from the females in the size and shape of the body. Males have wings while females are often wingless and resemble worker ants. The ovipositor is retractable and not visible when retracted.
