  S. 
  cecropia 
  Linn. 
  Occurs 
  throughout 
  the 
  State 
  June 
  to 
  August, 
  and 
  is 
  

   by 
  no 
  means 
  rare, 
  although 
  the 
  adult 
  is 
  not 
  often 
  seen. 
  The 
  larvae 
  

   feed 
  on 
  most 
  orchard 
  and 
  shade 
  trees, 
  and 
  also 
  on 
  grape 
  and 
  other 
  

   small 
  fruits, 
  sometimes 
  devouring 
  considerable 
  foliage, 
  and 
  yet 
  never 
  

   abundant 
  enough 
  to 
  do 
  any 
  material 
  injury. 
  The 
  cocoons 
  pass 
  the 
  

   winter 
  attached 
  to 
  tAvigs 
  or 
  some 
  other 
  support, 
  and 
  there 
  is 
  only 
  

   one

  The 
  larva 
  feeds 
  chiefly 
  on 
  sassafras, 
  but 
  also 
  on 
  a 
  

  

  large 
  variety 
  of 
  other 
  shrubs 
  as 
  well 
  as 
  fruit 
  and 
  shade 
  trees. 
  The 
  

  

  •

  and 
  wild 
  cherry. 
  

   The 
  cocoons 
  are 
  not

  "the

   silkworm," 
  and 
  while 
  by 
  no 
  means 
  rare, 
  is 
  never 
  plentiful 
  enough 
  

   to 
  do 
  conspicuous 
  injury. 
  The 
  cocoons 
  drop 
  to 
  the 
  ground 
  and 
  spend

  is 
  also 
  a 
  midsummer 
  brood.
