“…Dermestes species were bred in aggregations of 10 larvae [ 17 ]. Similarly, in the case of Necrobia rufipes (De Geer, 1775) (Coleoptera: Cleridae), there were 10 larvae per Petri dish [ 18 ].…”

Forensic entomologists frequently use a developmental method to estimate a post-mortem interval (PMI). Such estimates are based usually on the blow fly larvae or puparia. Data on their development is obtained by rearing them in colonies. In the case of beetles, which can be also useful for PMI estimation, development data is frequently collected by rearing them individually. However, some carrion beetles are gregarious, for instance, Necrodes littoralis (Linnaeus, 1758) (Silphidae). We compared mortality, rate of development and body size of emerged adult beetles reared individually and in aggregations. Mortality was much higher for beetles reared individually, particularly at low temperatures. The rearing protocol affected the time of immature development and the size of adult insects. Individually reared specimens developed much longer at 16°C, whereas at 20°C and 26°C development times of individually reared beetles were slightly shorter. Significant differences in the body size were observed only at 16°C; beetles that developed in aggregations were larger at this temperature. These findings demonstrate that aggregating is particularly beneficial for larvae of N. littoralis at low temperatures, where it largely reduces mortality and facilitates growth. Moreover, these results indicate that in forensic entomology the protocol of individual rearing is unsuitable for gregarious beetles, as it produces reference developmental data of low quality.

“…The pattern of mortality across temperatures is consistent with the patterns revealed for other forensically important beetles. In T. micans , T sinuatus , D. tessellatocollis , C. maxillosus and N. rufipes the highest mortality was observed at extreme temperatures 35 , 39 , 42 , 45 , 46 . The same pattern is reported in this study.…”

“…Models were created also for four species of Dermestidae : populations from south-western Europe of Dermestes frischi, D. undulatus and D. maculatus and Chinese population of D. tessellatocollis 41 , 42 . Developmental models were also published for central European population of Sciodrepoides watsoni (Leiodidae: Cholevinae) 43 , Chinese 44 and central European 45 populations of Creophilus maxillosus (Staphylinidae) and Chinese populations of Necrobia rufipes (Cleridae) 46 and Omosita colon (Nitidulidae) 47 .

Analysis of insects can provide evidence in death cases, for example, by answering the question about the time of death. Apart from flies, beetles are the second most useful insect group in forensic entomology. To elucidate the time of death based on insect evidence, developmental models of a given species are necessary. In this study, we developed such models for Necrodes littoralis, a necrophagous beetle, which is common in the Palearctic region and has great potential in forensic entomology. We monitored the development at 10 constant temperatures (14–30 °C). Larvae were reared in aggregations. Thermal summation models, isomorphen and isomegalen diagrams and growth curves were derived using the data. Depending on the temperature, development lasted between about 23 and 89 days. Mortality was high at the extremes of the temperature range. The thermal summation constant for the total development was 434.7 ± 28.86 accumulated degree-days above a developmental threshold of 9.04 ± 0.55 °C. This is the first comprehensive dataset on the development of N. littoralis. Implications for its use in forensic casework are discussed.

“…Among its conclusions were recommendations to increase levels of funding for both technological advances and foundational research in forensic science and to create a National Institute for Forensic Science, to set priorities and oversee research on forensic science. One response to these recommendations was the formation of the Forensic Capability Network, designed and developed under the Transforming Forensic Programme [74], with the challenging yet exciting task of delivering high quality forensic science in England and Wales.…”
