The postburial interval (PBI) can be inferred by using necrophagous insects colonizing the buried corpse. In different seasons, the species composition and succession of necrophagous insects on swine carrion (0.5-0.75 kg) buried at the depths of 30 cm and 60 cm in a Populus alba var. pyramidalis (Bunge, 1854) (Salicales: Salicaceae) grove of Shenyang, China from 2017 to 2019 were investigated. A total of 21 species of necrophagous insects belonging to 5 orders, 17 families were collected. Among them, the species of Phoridae and Platystomatidae were dominant at burial depth of 30 cm and 60 cm in summer and autumn. The species composition and time of colonization of necrophagous insects on the buried baits varied with seasons. Platystoma mandschuricum (Enderlein, 1937) (Diptera: Platystomatidae) and Aleochara puberula (Klug, 1833) (Coleoptera: Staphylinidae), the first arriving insects in spring, occurred on the baits for the longest time, from early June to early December. This work could provide reference data for the PBI estimation in Shenyang and similar geographical areas.

The age of the oldest immature insects present on a cadaver is typically used by forensic entomologists to estimate the minimum postmortem interval (PMI). The green bottle fly, Lucilia sericata (Meigen, 1826), known for its widespread distribution and necrophagy, is of considerable significance in forensic science. This study aimed to investigate potential regional developmental disparities between populations of L.

Estimating the postmortem interval (PMI) is critical in the field of forensic science, and necrophagous insects play a significant role in this process. (Fabricius) (Diptera: Calliphoridae) is a common necrophagous insect species, making its rapid and accurate identification essential. However, commonly used molecular biology methods, such as DNA barcode, still have some limitations in identifying necrophagous insects as they are often complex, time-consuming, and reliant on laboratory instruments.

The nocturnal behaviour and reproduction patterns of Sarcophagidae species during the scotophase are largely unexplored for species in the Neotropical region. The aim of this study was to assess the light regimes under which females of Peckia (Peckia) chrysostoma (Wiedemann, 1830) and Peckia (Sarcodexia) lambens (Wiedemann, 1830) would larviposit and understand how these variables influence intrauterine development in these flies. The experiments were conducted in an experimental room (lux = 100) in two independent experiments: I.

The present study reports new behavioral records for Oxysternon palemo Castelnau, 1840 in Cerrado. According to its nesting habits and resource allocation, this species of dung beetle is traditionally classified as coprophagous and paracoprid, transporting portions of dung through tunnels excavated below the resource. We observed a male individual moving a pequi seed (Caryocar brasiliensis Cambess.

Forensic entomology relies on known geographic ranges and seasonal presence of forensically relevant insects. In the Northeastern United States, there is no information on species in the region in early spring. Two forensic entomology workshops took place in April of 2023 and 2024 in Milton, Massachusetts.
