The biology and the prey function of Creophilus maxillosus as prey on fly larvae were studied in laboratory and in the nature.Creophilus maxillosus is one of important prey enemies of flies.In the laboratory (22-25℃)its eggs' duration is 4 days,larvae 14 days and pupae 16 days. This beetle breeds and lives in the corpse of poutries,fur and bone of animals,where flies also breed,but the mature beetle dweels in the soil at the depth of 3-8cm nearby their breeding place.Female oviposits in the soil at the depth of 1.5cm,producing an average of approximately 40 eggs one time.Matures prey their descendants and larvae prey each other when their food lacks.It is observered that mature,huried in 24 hours,can preys 13-15 third instar larvae of Lucilia sericata,and the larvae can eat 4 pupae in 24 hours.
