The adult female lays eggs, between 50 and 100, amongst
the material upon which the larvae will feed. The larva emerges from the egg and proceeds to feed.
Whilst feeding the larva of the clothes moth frequently constructs a loose silken 'shelter' which has attached to its many particles of debris and faecal pellets etc. Once mature the larva pupates. The pupa is reddish brown in colour. There is a certain amount of mobility in the abdomen of the pupa and it
twitches if disturbed. The adult emerges from the pupal case. Adult moths live for around 2 - 3 weeks.
In common with other insects, development times are influenced temperature, relative humidity, moistuer content, quantity and quality of food. Total life cycle at 23.5°C and 50% relative humidity is takes 63 days.
