A forensic case in which two facultative predatory species were found together on a human corpse is presented in this work. Second and third instar larvae of Synthesiomyia nudiseta (van der Wulp, 1883) (Diptera: Muscidae) and Chrysomya albiceps (Wiedemann, 1819) (Diptera: Calliphoridae) were collected from the dead body of a man on 14th November 2019, but puparia in the autopsy pictures were observed after, but not collected. The corpse was found on the terrace of the third floor of a building located in the town of Elche (SE Spain), and the pathologist confirmed the death as natural. The minimum post-mortem interval was estimated by the time to reach the length of the collected larvae or to reach the pupal developmental stage (in days and accumulated degree-days). In accordance with the influence of the predatory behaviour of each of these species on the developmental data of the other, as described in the existing literature, the effect of a hypothetical competition between both species on post-mortem interval was discussed.
