Larvae and pupae were collected from a muddy area in a stream margin at Sierra de la Ventana, province of Buenos Aires, Argentina, and reared in laboratory. Eggs were extracted from the abdomen of a gravid female from Encarnación, Paraguay. Larvae show characters states typical of carnivorous ceratopogonids that breed in mud.
