### Identification The Wardrobe Beetle (*Attagenus fasciatus*) is a pint-sized powerhouse of the Dermestidae family. Measuring a mere 3–5 mm, its body is a neat, elongated oval, typical of carpet beetles but more streamlined than its mottled cousins. Look for the defining field mark: a prominent, wavy transverse band (the *fascia*) of pale yellowish-orange scales crossing the dark chocolate-brown elytra. Unlike the solid-colored Black Carpet Beetle (*A. unicolor*), which lacks markings, or the Varied Carpet Beetle, which looks like a mosaic, *A. fasciatus* sports a distinct "belted" appearance that makes it stand out under a hand lens.
### Habitat & Range Truly cosmopolitan, this beetle has followed human commerce to every corner of the globe. While it thrives in temperate and tropical regions alike, it is a master of the "indoor ecosystem," frequently found in homes, textile warehouses, and museums. In the wild, you’ll find them in the high-protein environments of bird and mammal nests or tucked away in the dry, sheltered crevices of old tree bark where animal remains accumulate.
### Behaviour Observation requires a keen eye for light. Adults are heliophilic (sun-loving); you’ll often spot them on windowsills or visiting outdoor flowers like *Spiraea* for a nectar snack on warm afternoons. Conversely, the larvae are photophobic, scurrying into the dark at the slightest disturbance. These larvae—often called "woolly bears"—are slow-moving, reddish-brown, and possess a distinctive tuft of long hairs at their rear, which they can vibrate when threatened.
### Diet This species displays a fascinating dietary split. Adults are dainty foragers, feeding exclusively on pollen and nectar to fuel their flight. The larvae, however, are the "demolition crew." They are among the few organisms capable of digesting keratin. They forage through dried animal matter, including wool carpets, silk, fur, feathers, and even the chitin of dead insects.
### Fascinating Fact Despite their reputation as pests, *Attagenus fasciatus* larvae are "silent curators." If a single pair finds its way into a natural history museum, their offspring can reduce an entire collection of prize butterfly specimens to nothing but fine dust and bare pins in just a few weeks!
