The Dermestidae – Skin Beetles
The Dermestidae – Skin Beetles include a number of species that play a role in the decomposition of animal matter, but some species can also cause damage to property and collections, particularly to textiles, furs, bones, and preserved specimens. Here is a summary of their main characteristics:
Characteristics
Morphology:
Dermestids generally have an oval body, with elytra often decorated with patterns and various colors. They have club-shaped antennae composed of distinct segments. Their larvae, often referred to as “dermestid maggots,” are typically hairy and can be found in dark, hidden places.
Diet:
Dermestids are mainly necrophagous and saprophagous insects, meaning they feed on decomposing animal matter such as carcasses, skins, feathers, hair, fur, and organic waste. Some species are also attracted to dried products such as cereals, flour, and baked goods.
Habitat:
Dermestids can be found in a variety of habitats, including homes, museums, warehouses, attics, bird nests, and animal burrows. They are often associated with areas where organic material is decomposing or stored.
Potential damage:
While some dermestids have a useful role in decomposition, others can cause damage to property and collections, particularly in museums, entomological collections, libraries, and homes. Their larvae are known to damage textiles, furs, artworks, zoological specimens, and historical objects.
Life cycle:
Dermestids go through a complete life cycle, with egg, larval, pupal, and adult stages. The larvae are often the most destructive, as they actively feed on organic matter, causing significant material damage.
Prevention and control:
To prevent dermestid infestations, it is important to keep storage areas clean, monitor collections, use appropriate storage methods, and avoid conditions favorable to their development.
