Cecidosidae


Cecidosidae is a little-known family of primitive monotrysian moths in the order Lepidoptera which have a piercing ovipositor used for laying eggs in plant tissue in which they induce galls, or they mine in bark. Nine species occur in southern Africa, five species in South America and Xanadoses nielseni was recently described from New Zealand. Some minute parasitoid wasps are known.
