  When 
  fully 
  grown, 
  the 
  caterpillar 
  draws 
  two 
  leaves 
  together, 
  and 
  spins 
  a 
  stout, 
  

   clear, 
  white, 
  silky 
  web, 
  similar 
  to 
  many 
  BombycidcB, 
  in 
  which 
  to 
  undergo 
  its 
  

   .change. 
  It 
  is 
  remarkably 
  destructive 
  to 
  many 
  garden 
  plants, 
  particularly 
  to 
  

   ivy, 
  ferns, 
  various 
  species 
  of 
  Pelargonium, 
  and 
  the 
  pepper 
  tree 
  {Schinus 
  Molle). 
  

   It 
  is 
  not 
  unusual 
  to 
  see 
  large 
  plants 
  utterly 
  destroyed 
  by 
  their 
  attacks, 
  and 
  the 
  

   species 
  may 
  be 
  regarded 
  as 
  one 
  of 
  the 
  most 
  troublesome 
  pests 
  with 
  which 
  the 
  

   floriculturist 
  has 
  to 
  deal.
