Crowding larvae of Spodoptera littoralis (Boisd.) [= Prodenia litura F.] shortened the larval period but lengthened the pupal period. Crowding also reduced the pupal weight and the length of the body of the resultant adult, and produced darker coloured larvae. The type of food also affected the time taken to develop. When larvae are reared in isolation they are pale in colour, very inactive and hardly react to other larvae that touch them. Crowded larvae may be pale or darker in colour and show a number of reactions to one another on contact. They are more active than isolated larvae, and darker ones are more active than pale ones.
