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 usually basically white. The forewings each have a red and black line along the costa, and one or more black lines along the wing. The hindwings have a number of black spots, which may extend into each other in southern forms. The abdomen is usually red or 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.
