Figure 8.11 (a) Adult Dermestes maculatus feeding and laying eggs on a fresh dead rat. Although dermestid beetles are normally associated with dry remains, in absence of blowflies they will commence feeding on a dead animal within minutes of its death. (b) Characteristic frass produced by adult dermestid beetles when feeding on dry remains. (c) Localised rise in abdominal temperature of a dead rat associated with feeding by dermestid beetles and their larvae. The rise takes place long after the bloat stage of decomposition and no rise in temperature occurs in the absence of beetles. The rise in temperature is associated with the point at which the insects start feeding on the tissue surrounding the temperature data logger.
