From midtime of April to the beginning of October, Muscadomesticauicina could be seen on the cadvers, however, Aldrichiragrahormi only could be seen before the beginning of May. Otherwise, Lucilia sericata, C. Megacephala, S. fuscicauda could be seen on the cadvers from March to the end of October. After the midtime of November, none of sarcosaphagous flies could be seen on the cadvers. On the other hand, maggots of sarcosaphagous flies could be seen often on the cadvers after adults of sarcosaphagous flies intruding 1 to 4 days, relating to temperature of environment.
