  Family 
  MUSCIDzE. 
  

  

  This 
  family 
  contains 
  the 
  common 
  house-fly, 
  the 
  stable 
  fly, 
  the 
  horn-fly, 
  

   the 
  blow-fly 
  and 
  similar 
  well-known 
  insects. 
  All 
  of 
  these 
  have 
  the 
  an- 
  

   tennal 
  bristle 
  hairy 
  or 
  plumose 
  to 
  the 
  tip, 
  but 
  have 
  no 
  spines 
  on 
  the 
  

   abdomen 
  except 
  at 
  the 
  end, 
  about 
  the 
  anal 
  segments. 
  

  

  The 
  larvae 
  of 
  these 
  flies 
  are 
  true 
  maggots, 
  and 
  with 
  few 
  exceptions 
  they 
  

   live 
  in 
  decaying 
  material 
  of 
  all 
  kinds, 
  excrement, 
  putrid 
  meat, 
  garbage, 
  

   etc. 
  Eggs 
  are 
  laid 
  in 
  masses 
  and 
  hatch 
  in 
  a 
  few 
  hours, 
  the 
  larval 
  life 
  

   being 
  often 
  scarcely 
  a 
  week. 
  

  

  As 
  scavengers 
  these 
  insects 
  are 
  useful, 
  but 
  they 
  become 
  a 
  nuisance 
  in 
  

   the 
  house 
  and 
  in 
  the 
  stable. 
  While 
  the 
  majority 
  of 
  the 
  flies 
  gain 
  their 
  

   living 
  by 
  scraping 
  and 
  lapping 
  liquid 
  or 
  pasty 
  foods, 
  a 
  few 
  of 
  them 
  are 
  

   blood-suckers, 
  the 
  mouth 
  being 
  developed 
  for 
  piercing 
  and 
  sucking. 
  

  

  POLLENIA 
  Desv. 
  

  

  P. 
  rudis 
  Fab. 
  Common 
  throughout

  the 
  common 
  house-fly, 
  but 
  is 
  also 
  found 
  on 
  windows, 
  especially 
  

   in 
  late 
  summer. 
  

  

  CHRYSOMYIA 
  Desv. 
  

  

  C. 
  macellaria 
  Fab. 
  Common

  the 
  larva 
  of 
  

   this 
  fly,

  as 
  the 
  screw-worm, 
  has 
  done 
  great 
  harm 
  in 
  the 
  south- 
  

   west, 
  but 
  is 
  not 
  injurious 
  in 
  New 
  Jersey.
