About Dermestes maculatus DeGeer, 1774
Dermestes maculatus DeGeer, 1774 adult beetles measure 5.5–10 mm in body length. They are primarily black, with a band of white hairs on either side of the pronotum. Their antennae terminate in 3-segmented clubs. The apices of the elytra are serrated, and each ends in a small projecting spine. The underside of the abdomen is mostly white, with black spots along the sides and at its terminal end. Larval bodies are covered in setae. The ventral surface of the larval abdomen is yellowish-brown, while the dorsal surface is dark brown, typically marked with a yellow line running down the middle. Two urogomphi, which are horn-like protrusions, are located on the upper surface of the larva’s last abdominal segment; these structures curve upward and away from the tip of the abdomen. Pupae are oval-shaped, usually smaller than larvae, and lack setae. Most pupae retain the final larval skin as a protective covering.
