   Family 
  DOLICHOPODID^. 
  

  

  Small, 
  usually 
  shining 
  green, 
  sometimes 
  black 
  or 
  yellow 
  flies, 
  with 
  

   short 
  antenna, 
  plump 
  body 
  and 
  comparatively 
  long 
  legs, 
  which 
  are 
  often 
  

   contrasting 
  yellow 
  or 
  brown. 
  The 
  tarsi 
  or 
  feet 
  are 
  unusually 
  long, 
  whence 
  

   they 
  are 
  called 
  "long-footed 
  flies," 
  and 
  in 
  the 
  male 
  the 
  anterior 
  pair 
  are 
  

   often 
  flattened 
  or 
  otherwise 
  modified. 
  In 
  the 
  same 
  sex 
  the 
  abdomen 
  is 
  

   frequently 
  furnished 
  with 
  curiously 
  complex 
  claspers, 
  which 
  are 
  bent 
  

   down 
  beneath 
  the 
  body. 
  In 
  the 
  female 
  there 
  is 
  usually 
  a 
  pointed, 
  flat 
  

   ovipositor. 
  They 
  are 
  predatory 
  in 
  habit, 
  feeding 
  chiefly 
  upon 
  smaller 
  

   flies. 
  Ttie 
  larvae 
  are 
  long, 
  slender, 
  cylindrical 
  and 
  feed 
  on 
  decaying 
  

   vegetation.
