dermestid

Dermestid is a common name for a family of beetles, Dermestidae. These small, oval-shaped insects are known for their ability to consume dried animal matter. Their diet typically includes keratin, found in hair, fur, feathers, and dead insects, as well as dried plant material. This makes them significant decomposers in many ecosystems.

Dermestids are often found in homes, museums, and storage areas where they can infest stored food products, carpets, woolens, and taxidermy specimens. Certain species, such as the larder beetle (Dermestes lardarius) and the black carpet beetle (Attagenus unicolor), are considered pests due to the damage they can cause to household items and stored goods. In contrast, other dermestid species play a vital role in nature by cleaning carcasses, facilitating the decomposition process.

In scientific contexts, dermestids are frequently used in forensic entomology to help determine the time of death of a body. Their presence and developmental stage on remains can provide crucial evidence for investigators. Museums also utilize dermestids for cleaning skeletal remains and preparing specimens for display or research. The larvae are often more destructive than the adults, as they are voracious feeders. The life cycle involves egg, larva, pupa, and adult stages.
