clothes moth whose larva eats the oldest wool in the wardrobe

Size
Length: 1–1.5 cm
Lifespan
1–2 years
Diet
Larvae feed on keratin-based materials: wool, fur, feathers, silk and felt. Adults do not feed (no functional mouthparts). Pest of natural fibre clothing and carpets.
Habitat
The wardrobe specialist, found almost exclusively in human dwellings. Prefer dark, undisturbed areas like back of a closet or underneath heavy furniture.
Range
Throughout North and South Islands in human dwellings, museums and storage areas. Most common in urban and suburban areas where natural fibres are present.
Endemism
Introduced
Main Threats
None. This introduced pest is widespread. Controlled in households using traps, cleaning and natural repellents like cedar and lavender.
Population
A global traveler that followed humans to New Zealand. One of the few insects that can thrive in the biological desert of a modern, dry-cleaned household.
Conservation Status
Introduced
The invisible eater of history. The common clothes moth is a specialised resident of the domestic shadow. These small, golden-buff moths are defined by a biological strategy that avoids the light. While the males are occasionally seen in a fluttering, frantic search for a mate, the females prefer to scuttle through the dark, undisturbed corners of the home. Remarkably, the adults do not possess functional mouthparts and do not feed at all, focusing their short lives entirely on reproduction. All the subtle destruction associated with this species is carried out by the creamy-white larvae, which possess the rare metabolic ability to digest keratin, the tough, fibrous protein found in wool, silk, feathers and hair. As urban scavengers, clothes moths represent a successful evolutionary transition from the abandoned bird nests of the wild into the climate-controlled environments of high fashion. Their life cycle is a definitive sign of hidden hunger, where an expensive merino jersey is viewed not as a garment but as a massive and concentrated pile of protein. The larvae often spin loose silken tunnels or mats as they feed, remaining hidden within the fibres they consume. The female lays her eggs directly on suitable materials. When the larvae hatch, they begin feeding immediately, leaving behind irregular holes and webbed patches of silk. This existence is a testament to the persistence of the domestic, illustrating how a species can thrive by capitalising on the very materials humans value most. They act as a living reminder that our homes are active biological arenas where the ghosts of the closet are always looking for a chance to reclaim natural fibres for the earth. Not threatened, the clothes moth serves as a primary motivator for the maintenance and preservation of natural textiles. To encounter a golden-buff moth in a darkened hallway is to witness a survivor that has mastered the art of the hidden hunger, a creature that proves that even in the most modern home, the ancient laws of scavenging and recycling are never far away.
