On human corpses and animal carcasses, predominantly Diptera (flies) and Coleoptera (beetles) are found. Determination of the insect fauna that is forensically relevant in Turkey is required for forensic investigations since such baseline data currently do not exist. The aim of this study is to identify the necrophagous specimens associated with suspicious human deaths in order to determine the fauna of Ankara and its surrounding cities and to estimate the postmortem interval by using the method of accumulated degree days and hours. Insect evidence gathered from 16 sets of human remains across Turkey from 2006 to 2013 was examined. In total, 516 samples were collected. Of that total number, 428 of them were identified as blow flies, 70 were flesh flies, 9 were filth flies, 5 were flies belonging to the Heleomyzidae, one of them was a clown beetle (Histeridae) and 3 were carrion beetles (Silphidae). This is the first comprehensive study associating human corpses with forensic entomology in Turkey.
