Crocidolomia pavonana is a moth of the family Crambidae.
Its caterpillar is a crop pest and is known as the croci or the cabbage cluster caterpillar. The larvae feed on Brassicaceae species and are considered an agricultural pest on cabbages.
At first, they feed only on the undersides of the leaves. Later they feed on the rest of the leaves and the central shoot. The species was first described by Johan Christian Fabricius in Both are rather variable in colouring but have brownish markings on a cream background. The male can be distinguished by the tufts of dark-coloured hairs at the front of the forewings.
The larvae are grey with dark heads when they hatch and later become green with dark heads and five fine pale yellow longitudinal stripes. The pupa is cylindrical, olive green to light brown, becoming darker shortly before emergence. It is surrounded by a silken cocoon.
Crocidolomia pavonana is found in the tropical and subtropical areas of Africa, Asia and Australia. Host plants eaten by the larvae include the brassicaceous plants Brassica oleracea and Crocdolomia rapa and their varieties, but also cotton Gossypiumpigeon pea Cajanus cajanGynandropsisnasturtium Tropaeolum and radish Raphanus.
The eggs take about four days to hatch. The young larvae feed on the underside of the leaf on which they hatch before moving on to other parts of the plant. They pass through five instars over a period of about twelve days,  burrowing into the centre of the plant after about four days. If the apical meristem is damaged, multiple heads may be produced or the plant may die.

Several parasitoids are known to attack the larvae of this moth in different parts of its range. These include braconid wasps and tachinid flies, and in India the larvae are preyed on by a predatory bug in the Pentatomidae family. From Wikipedia, the free encyclopedia.
