Chrysomya rufifacies is an important blowfly species used to estimate the postmortem interval of corpses. Chrysomya rufifacies eggs were submerged in water for 1 minute, 3 minutes, 5 minutes, 7 minutes, and 10 minutes to see if the eggs can survive being submerged in water. The number of successfully hatched eggs was recorded and there was only a significant difference with the 10 minutes treatment. Based on the results, C. rufifacies eggs can tolerate water until 10 minutes of submergence. This result can mean that even though C. rufifacies eggs can tolerate water, their emergence can be affected by water after 10 minutes of submergence. This is the first experiment that deals with the drowning of C. rufifacies eggs which is important for the emergence time that helps estimate the PMI of a corpse.
