Skin beetles

Definition

A common name for beetles of the family Dermestidae (Coleoptera), referring to their habit of feeding on dried animal remains, hides, skins, and keratin-rich materials. The name distinguishes them from other dermestid common names such as carpet beetles (Anthrenus spp. and relatives), larder beetles (Dermestes spp.), and khapra beetles (Trogoderma granarium), though these categories overlap ecologically and taxonomically. Skin beetles are economically significant as pests of stored products, museum collections, and forensic interest as colonizers of carrion.

Etymology

From the feeding habit of larvae and adults on dried animal skins, hides, and proteinaceous materials.

Example

Dermestes maculatus and related species are classic skin beetles used in forensic entomology to estimate postmortem interval based on their predictable colonization of human remains.

Synonyms

• dermestids
• carpet beetles (partial overlap)
• hide beetles (partial overlap)

Related Terms

• Dermestidae
• carpet beetles
• larder beetles
• Khapra beetle
• Forensic entomology
• museum pests
• keratinophagy
• carrion beetles

Usage Notes

The term is somewhat interchangeable with 'hide beetles' and overlaps with 'carpet beetles,' though specialists often reserve 'skin beetles' for species associated with dried animal products rather than woolens and fabrics. In museum contexts, 'dermestid' is preferred for precision. Not all Dermestidae are skin beetles—some feed on pollen, nectar, or plant material, particularly in tropical lineages.
