Dermestidae is a family of beetles comprising approximately 1,700 to 1,800 described species worldwide. Adults are small (1–12 mm), typically oval to rounded, with antennae that are clubbed and usually concealed in thoracic grooves. The family exhibits exceptional diversity in feeding ecology: larvae of most species are scavengers specialized on dry organic matter, particularly keratin-rich materials including animal hair, feathers, hides, wool, and silk. Certain genera have evolved highly specific associations, such as Thaumaglossa in mantid egg cases. The family includes significant economic pests (carpet beetles, khapra beetle), forensic indicators (hide beetles), and beneficial species used in taxidermy and museum specimen preparation. Larvae of subfamily Megatominae possess distinctive defensive hastisetae—barbed, spear-tipped setae that detach to entangle predators.
Megatoma
Megatoma is a genus of dermestid beetles (family Dermestidae) distributed across the Palearctic, Near East, and Nearctic regions. The genus contains approximately 23 described species, including the well-studied Megatoma undata (Linnaeus, 1758). Species within this genus are associated with stored products and natural habitats where they feed on dried organic matter. Larval stages have been documented in detail for some species, showing characteristic dermestid morphology with specialized setae.
