This is a well known insect order.The eggs hatching into free-living, active larvae which poses abdominal pro-legs and are known as caterpillars.

Often pupate inside silken cocoon. Adults feed harmlessly (if at all) on nectar from flowers.

Their larvae does the damage to clothes, stored products etc.

Common clothes moth:

Moderately common pest of animal derived fabrics, furs and feather products. Also occasionally found in food storage premises. They are able to survive and successfully infest some dried vegetable materials.

Adults can reach up to 7mm in length. Clothes moths rarely fly to lights at night instead prefer darkness.

Females do not fly and the male occasionally. Female lays approximately 100-150 eggs on surface of fabrics which will hatch into larvae in approximately 5 days. The larvae development period depends considerably the condition of the surrounding environment. These moths are often indicating of poor hygiene conditions.

Spilt food stuff and other waste material should be thoroughly cleaned up where old bird nests are present they should be removed and burnt. Examine closets and storage goods for larvae cases, moths and damages to locate the source of infestation before treatment. A residual insecticide can then be applied to walls, ceilings, floors and around carpet edges. In domestic premises the frequent use of a vacuum cleaner around edges should reduce the risk of infestation.

A few pupae immediately.

Significant stored food pest causing contamination by silk and frass (droppings) and some direct damage.

For treatment monitor with pheromone traps, residual spray on structure and appropriate time to kill resting adults or migrating larvae.
