Larval Growth of flesh fly Sarcophaga bullata andcarnaria (Diptera: Sarcophagidae) was Studied in outdoor ambient temperatures in winter seasons.Thevarious types of physical evidence can be found at almost any crime scene and detailestimation of post mortem interval (PMI) in the investigation of distrustful death, the forensic measurer flesh flies are essential for accuracy in estimation of PMI. The types of evidence and where it is found can assist investigators to develop a sense of how the crime was committed. The family sarcophagidae species of Sarcophaga Bullata & Sarcophaga Carnaria. Were reared in laboratory condition for studying their time duration of different stages of life cycle under the fluctuating temperature in winter seasons. Sarcophaga Bullatatook225 hours 35 minutes, whereas the Sarcophaga Carnariatook 240 hours 33 minutes, during winter season respectively. This study shows that forensic investigators will have to take each of these variables into consideration from thedevelopment of insects in orderdiptera to give clear or exactestimation of postmortem interval.
