Larvae feed on various Asteraceae species, including "Ageratum houstonianum", "Bidens pilosa" and "Calendula officinalis". The young larvae are smooth and green with a brown head. Later instars develop a purple herring-bone pattern with a black head. Finally they turn brown with a thin wavy white line along each side, and white spots. Pupation takes place in the soil.References:
