Dermestidae

Dermestidae, commonly known as the carpet beetles or larder beetles, are a family of Coleoptera, or beetles. These insects are characterized by their small size, typically ranging from 1 to 12 millimeters, and their oval or elongated body shape. The larvae of dermestids are often hairy and grub-like, and it is the larval stage that is responsible for most of the damage attributed to this family.

Adult dermestids are often dull in color, with brown or black being common, though some species exhibit metallic iridescence. They possess clubbed antennae. The larvae, however, can be quite distinctive, with tufts of bristles that can cause irritation in some individuals upon contact.

Dermestidae are found worldwide and are widespread in their habitats. They are often associated with stored products, human dwellings, and animal remains. Their diet is a key characteristic; many species feed on dry animal matter, including keratin-rich substances like hair, wool, silk, fur, and feathers. This dietary preference makes them significant pests in homes, museums, and textile storage facilities, where they can damage clothing, carpets, upholstery, and preserved specimens. Other species feed on pollen, dead insects, or carrion.

The life cycle involves egg, larval, pupal, and adult stages. Females lay eggs in suitable food sources. The duration of the life cycle can vary greatly depending on the species, temperature, and food availability, but can range from a few months to over a year. Their ability to digest keratin makes them ecologically important in the decomposition of animal matter in natural environments.
