Insect traces and the mummies of Palermo – a status report 73 Entomologie heute 31 (2019): 73-93 Insect Traces and the Mummies of Palermo – a Status Report Insektenspuren und die Mumien von Palermo – ein Statusbericht KRISTINA BAUMJOHANN & MARK BENECKE Summary: In an inter-disciplinary investigation of the mummies of the Capuchin Monastery in Palermo we made entomological fi ndings with regards to the comparatively poor state of preservation of the deceased, to provide enlightenment about the process of natural mummifi cation, as little is known about how the bodies were handled after death until they were laid out in the basement. Three groups of insects could be found on the bodies that are in accordance with the conditions described and the storage situations in the monastery of Palermo: corpse colonisers, pests and predators. This is our fi rst status report on the topic. Keywords: Palermo, mummies, insects, forensic entomology, archaeoentomology, feeding traces, decomposition Zusammenfassung: Bei einer interdisziplinären Untersuchung der Mumien des Kapuzinerklosters in Palermo wurden von uns insektenkundliche Befunde erhoben, um den vergleichsweise schlechten Erhaltungszustand der Verstorbenen wie auch den Vorgang der natürlichen Mumifi zierung zu erhel- len, da über den Umgang mit den Körpern nach Todeseintritt bis zur Aufbahrung im Keller wenig bekannt ist. An den Leichen konnten drei Insektengruppen gefunden werden, die im Einklang mit den geschilderten Bedingungen und Aufbewahrungssituationen im Kloster von Palermo stehen: Leichenbesiedler, Lästlinge und Räuber. Dies ist unser erster Lagebericht über diese Thematik. Schlüsselwörter: Palermo, Mumien, Insekten, forensische Entomologie, Archäo-Entomologie, Fraßspuren, Verwesung 1.
