All species are reddish brown with circular, silvery-white spots on the fore wing. The genus has been placed in the Cossidae, Sesioidea and Pyraloidea by various authors. The biology of D . actinias was briefly described by Turner (1902); the larvae are stem-borers which excavate a tunnel to the outside bark prior to pupation and the pupae are protruded from the larval tunnel before eclosion. The only known host plant is Canthium attenuatum .
