Blowfly (Diptera: Calliphoridae) identification is a pre-requisite to the field of sanitary biology, medical, veterinary, and forensic entomology. The specimens were collected using fly traps in eight regions of Fars province, Iran. A total of 10 species belonging to four genera were recorded out of which Calliphora pattoni Aubertin, 1931 and Chrysomya phaonis (Seguy, 1928) are new records for the country.
