The Caterpillar of this species is dark brown with cream spots, and has lots of brown stiff hairs. It has been found feeding on various herbaceous plants, from the families:
The head, thorax, and wings of the adult moth are basically white. The forewings each have a red and black line along the costa. The hindwings have a number of black spots. The abdomen is usually red, but can be yellow, with a black mark on top of each segment. The wingspan is 4 to 5 cms. The markings on the wings are quite variable. The red in the costal lines of the forewings can be orange or yellow.
