Sarcophaga peregrina (Robineau-Desvoidy, 1830) play a pivotal role in forensic entomology, particularly in the context of decomposing corpses in South Korea, with its prevalence most notable from May to October. This study aims to leverage the growth metrics of S. peregrina to refine estimates of the minimum post-mortem interval (PMI_min), thereby providing a more localized and accurate measure of the time elapsed since death. By cultivating specimens a across a range of temperatures (22℃, 25℃, 28℃, and 34℃), we documented the corresponding larval and pupal development rates, observing significant variances in development times across temperatures: 475.1 hours at 22℃, 347.0 hours at 25℃, 326.0 hours at 28℃, and 247.3 hours at 34℃. Our findings highlight a temperature-dependent acceleration in life cycle progression of research emphasizes the importance of considering environmental factors, particularly temperature, to enhance the accuracy of forensic investigation.
