The orchid dupe wasp is a medium sized wasp with mainly orange body and dark wings. The abdomen has broad black band with four white spots on each side. The long thin antennae curl upwards at the ends. Females have a stout black ovipositor that is about half the body length. It is called the Orchid Dupe because some species of orchids mimic the odour and appearance of female Lissopimpla wasps. The male Lissopimpla wasps mistake the flowers for females pollinating the orchid.
