Young larvae feed gregariously on the underside of the leaf of their host plant protected by a thin web of silk. At first they eat the substance of the leaf and leave the opposite epidermis. They soon scatter more or less, and make hiding places by fastening together the lower edges of coconut leaflets. Often several caterpillars can be found in the same place. As they become slightly larger, they eat the whole substance, eating from the edge, and not leaving the epidermis. When the leaflet is mostly eaten, they migrate to other leaflets. Larvae are full grown in about four weeks from hatching. Full-grown larvae are 32–35mm long and dull greenish, with two dorsal whitish lines.
Pupation takes place in a slight cocoon in the caterpillar's retreat. The pupa is 15–19mm long and light to dark brown according. The pupal period lasts 11–13 days.
The beet armyworm or small mottled willow moth is one of the best-known agricultural pest insects. It is also known as the asparagus fern caterpillar. It is native to Asia, but has been introduced worldwide and is now found almost anywhere its many host crops are grown. The voracious larvae are the main culprits. In the British Isles, where it is an introduced species and not known to breed, the adult moth is known as the small mottled willow moth.

The Coconut black headed caterpillar, is a species of moth found in throughout East Asian countries including Bangladesh, India, Sri Lanka, Myanmar, as well as Indonesia. It is considered a pest of coconut palm trees, causing considerable damage to the trees, and reducing the plant's yield significantly and can be a major problem where coconuts contribute to the economy. The species exists on coconut palms through its life stages from larval to moth, and utilizes the tree fronds as a main source of nutrition. Various methods of control have been explored, yet the primary control method is the administration of pesticides directly to the root of the coconut palms.
