Hide Beetle

Dermestes maculatus, known as the hide beetle or leather beetle, belongs to the family Dermestidae, order Coleoptera. Adults are typically 5.5-10 mm in length, oval-shaped, and dark brown to black dorsally, with a distinct pale yellowish-grey pubescence on the ventral surface and lateral margins of the pronotum, which is diagnostic. Larvae are elongated, dark brown, covered with prominent hairs, and possess two characteristic horn-like spines (urogomphi) on the caudal segment. They can grow up to 15 mm. Eggs are white and spindle-shaped. The life cycle, from egg to adult, is relatively rapid under optimal conditions (25-300C, 60-70% RH), completing in 30-60 days; however, it can be extended by cooler temperatures or food scarcity.

Hide beetle larvae are voracious feeders on dried animal products with high protein content, including hides, skins, dried fish, meat, pet food, and museum specimens. Adults also feed on similar materials but are generally less destructive than larvae. Larvae tend to bore into substrates for pupation, often causing additional damage to non-food materials like wood or insulation. Adults are strong fliers and are attracted to light. Mating occurs on or near food sources. They can infest a wide range of materials in storage and processing facilities. Dispersal is often through movement of infested commodities.
