The nutritional composition and moisture contents were determined every two weeks using proximal analysis in an experiment that lasted 56 days. Dermestes maculatus DeGee. The life cycle of Dermestes maculatus on either a carcass in dry-decay or in stored animal products requires approximately five to seven weeks to complete under optimum conditions. Dermestid beetles and some other insect pests associated with stored silkworm cocoons in India, including a world list of dermestid species found attacking this commodity. Forensic Science International 120: 15-17. Once adults, the beetles can disperse to other food sources by flying (Haines and Rees 1989). D. maculatus is easily colonized as they undergo a complete metamorphosis from larva to pupa to adult in about 30 days at optimal conditions. D. frischii: Dermeste destructeur du cuir [Fr]. The underside of the abdomen is typically yellowish-brown while the dorsal surface is typically dark brown, usually with a central yellow line. Cloud JA, Collison CH. This article discusses the ability of adults of the coleopteran beetle Dermestes maculatus (De Geer) to colonise fresh remains. Schroeder H, Klotzbach H, Oesterhelweg L, Püschel K. 2002. In the laboratory, adult D. maculatus instantly colonised fresh killed rats and mice. Dermestes spp. While the adults have been detected at early stages of decay, the larvae are the life stage used for post-mortem interval estimation. mg ai/m:! The macerated catfish in each group were infested with Dermestes maculatus larva in 3 replicates per group. Figure 5. Larvae feed on carcases, and stored sheepskins, leather , Mature larvae may bore into hard surfaces, especially softwoods, to pupate 1996. 2 Kodiak Bones & Bugs Taxidermy uses the Dermestes maculatus, which has a lifespan of four to five months and goes as follows: Dermestid beetle eggs hatch in four days. Due to their ability to clear skin and hair off bodies cleanly, Dermestes maculatus can be used to clean bones to assist with forensic cases.

Experiments with captive hide beetles, Dermestes maculatus DeGeer, reveal that exposed pupae are frequently cannibalised by larvae when they are unable to seek protection in a pupal chamber. The aim of this work was to determine if the depressions produced on bones by these beetles could be product of pupation. Illustration of Dermestes maculatus from Edmund Reitter "Fauna Germanica" The bodies of the larvae are covered in setae.
