title: [Estimation time of death by necrophagous flies life cycle].
abstract: OBJECTIVE
  To study the nature of necrophagous flies, their developmental cycle and seasonal variation.
  
  
  METHODS
  Animal corpse was used to be baiting. Eight kinds of necrophagous flies on their developmental cycle and the pattern of seasonal variation were analyzed.
  
  
  RESULTS
  The community of necrophagous flies at high temperature in summer were more abundant than at low temperature in winter. Eight necrophagous flies through longer time at high temperature during every state than at low temperature.
  
  
  CONCLUSIONS
  The life cycle and seasonal variation pattern of necrophagous flies could be used to estimate the time of death in practical cases.
