  When 
  Clemens 
  described 
  the 
  American 
  grape-berry 
  moth 
  in 
  1860 
  

   he 
  recorded 
  it 
  as 
  having 
  several 
  food 
  plants 
  and 
  made 
  the 
  following 
  

   statements 
  concerning 
  the 
  habits 
  of 
  the 
  larva 
  : 
  

  

  The 
  larva 
  feeds 
  on 
  the 
  fruit 
  of 
  the 
  grape 
  in 
  September; 
  a 
  silken 
  gallery 
  is 
  attached 
  

   to 
  the 
  external 
  opening 
  of 
  the 
  fruit. 
  Its 
  head 
  is 
  dark 
  brownish; 
  shield 
  blackish; 
  body

  moth 
  (Polychrosis 
  viteana). 
  (Original.) 
  

  

  immaculate 
  dark 
  green. 
  It 
  may 
  likewise 
  be 
  taken 
  on 
  the 
  fruit 
  of 
  wild 
  raspberry. 
  The 
  

   individual 
  feeding 
  on 
  the 
  grape 
  undergoes 
  transformation 
  by 
  weaving 
  a 
  cocoon 
  on 
  the 
  

   surface 
  of 
  the 
  ground 
  and 
  that 
  from 
  the 
  raspberry 
  under 
  an 
  excised 
  and 
  turned 
  down 
  

   portion 
  of 
  leaf. 
  This, 
  however, 
  may 
  not 
  be 
  its 
  normal 
  habit. 
  

  

  Clemens 
  also 
  records 
  it 
  as 
  feeding 
  on 
  leaves 
  of 
  sassafras. 
  

  

  Since 
  that 
  time 
  a 
  number 
  of 
  other 
  entomologists 
  have 
  added 
  several 
  

   food 
  plants 
  to 
  this 
  list. 
  Packard, 
  in 
  1868, 
  stated 
  that 
  the 
  first 
  brood 
  

   feeds 
  on 
  the 
  leaves 
  and 
  tendrils 
  of 
  the 
  grape. 
  

  

  Slingerland 
  gives 
  the 
  following 
  list 
  of 
  food 
  plants 
  added 
  by 
  ento- 
  

   mologists 
  during 
  the 
  next 
  thirty 
  years 
  : 
  

  

  Blackberry 
  blossoms 
  (Riley, 
  1870), 
  roses 
  and 
  Vernonia 
  or 
  iron 
  weed 
  (Murtfeldt, 
  1880 
  

   and 
  1882), 
  tulip-tree 
  leaves 
  and 
  swollen 
  stems 
  of 
  Amorpha 
  (Fernald, 
  1882), 
  flower-buds
