The preliminary survey of the entomofauna on decomposing carrions in Warri was undertaken to provide a baseline insect information on carrion decomposition. Seven rabbits (Orytctolaguscuniculus) of mean weight 2.14±0.12kg (M±S.D) sacrificed by cervical dislocation were monitored for 45 days from January, 7th and February 21st, 2017 with daily observation and collection of invading insects. The results obtained revealed four (4) identifiable stages of decomposition (fresh decay, bloated, wet decay, and dry decay) even though the entire decomposition process was a continuous one. Insect species from three (3) Orders i.e. Diptera, Coleoptera and Hymenoptera and fourteen families were consistently sampled. Most species from Diptera and Coleoptera were of forensic importance as they used the carrions as breeding ground thus providing a biological tracking template for a possible estimate of time since carrions were killed or exposed. The Hymenopteran species were mainly opportunistic, as they used carrions for food and temporary shelter. It is suggested that further work be carried out within the Warri metropolis and other areas in order to obtain all likely insects of forensic importance unique to the areas.
