Beetles (Coleoptera) are recognized as important entomological clues in the forensic entomology field for the determination of post-mortem interval (PMI). The necrobiont nitidulid species of beetles are colonizers of human corpses in the advanced stages of decomposition which provide essential complementary data to estimate the PMI in forensic cases. We report the new finding of Palearctic sap beetle, Nitidula flavomaculata Rossi 1790, adults from a mummified human body located outdoor in a xeric mountain setting, north of Shiraz, the capital city of Fars province, Iran. This human corpse was a male discovered in December 2014. Adult beetles of N. flavomaculata were allowed to nourish, copulate and lay eggs in a rearing container at 23±1 °C. The time period from oviposition to the next F1 generation of egg-laying adults lasted 61 days. The species of beetle found in this case could be used in forensic investigations particularly during the cold season in future.
A mummified human corpse and associated insects of forensic importance in indoor conditions
International Journal of Legal Medicine
We report, for the first time from Poland, the presence of Dermestes haemorrhoidalis (Coleoptera: Dermestidae) on a mummified human corpse found in a flat (Lower Silesia province, south-western Poland). Different life stages of D. haemorrhoidalis were gathered from the cadaver, and the signs of activity of these beetles (i.e. frass) were observed. On the basis of these facts, we concluded that the decedent, whose remains were discovered in the flat on 13 December 2018, died no later than the summer of 2018, with a strong probability that death occurred even earlier (2016 or 2017). A case history, autopsy findings, and entomological observations are provided. The presence of larvae of Dermestidae in the empty puparia of flies is reported for the first time. A list of the invertebrate species found in the corpse is provided, compared with available data, and briefly discussed.
Beetles (Coleoptera) have been recognized as significant entomological evidence in the forensic entomology field in estimating the postmortem interval (PMI). We report on the colonization of an adult human corpse by three beetle species in Sadra district, Fars province, south of Iran. The adults of Creophilus maxillosus, Dermestes frischii and Hister sp were all collected from the victim’s body which had been wrapped in a sack. For the life cycle study, Creophilus maxillosus (Coleoptera: Staphylinidae) adult beetles were allowed to feed, mate and oviposit in rearing chamber (11 × 9 cm) at 23 ± 1°C. Development rates from the instance mates placed together to the emergence of adults was 41 days. Information from this study can be helpful in forensic entomology study.

SUCCESSION AND LIFE CYCLE OF BEETLES ON THE EXPOSED CARCASS
Various species of insects attract on the dead and decomposing body in a sequential manner, thisprocess is termed as succession. Necrophagous insects mainly Coleopterans are attracted to carcasses at specific stages of decomposition. Many types of beetles arrive on carcasses mainly belong to family Histeridae, Dermestidae, and Cleridae. Dermestid beetles feed on various things like animal’s decomposing remains and skin etc. Dermestid beetles are elongate broadly oval, covered with hairs or scales, with short, clubbed antennae fitted in grooves and of black or brownish colour. Beetle specimens were collected from exposed animal carcasses in Kanpur city and prepared for farther taxonomic study. The investigation started from February2012 to January2013. Most of the specimens collected were found in abundance during spring and summer season. In this investigation, succession and life history of the species Dermestes maculates (family: Dermestidae) is elaborated. As the PMI is based on the lifecycle and behaviour of necrophagous insects, this study may help as an important tool for estimation of the post-mortem interval (PMI) in forensic science.
