Description

Adult wingspan is about 19 mm.[7] The female lays eggs between veins on the undersides of leaves of the food plant. The caterpillar is translucent yellowish green. First two pairs of legs are black. The larvae roll or web the leaves of the food plant together, feeding on them within this shelter. They sometimes live in flowers.[8] Pupation takes place inside a rolled leaf, which is lined by a thin layer of silk. The pupation period lasts one to two weeks. Adult has pale brownish forewings with various dark markings. Hindwings are plain brown. On thorax region, there is a crest of dark scales.[9]

Control and management

Adults and caterpillars can be controlled by hand picking and pruning. Egg and larval parasitoids are also effective. Pesticides and use of Bacillus thuringiensis extracts are effective against caterpillars.[1]
