  color 
  is 
  rather 
  inclined

  being 
  frequently 
  of

  The 
  caterpillar, 
  according 
  to 
  Sepp, 
  shortly 
  after 
  it 
  is 
  hatched, 
  selects 
  a 
  nettle- 
  

   leaf, 
  which 
  it 
  draws 
  together 
  with 
  threads 
  into 
  a 
  rouudish 
  hollow 
  form, 
  leaving 
  

   for 
  the 
  most 
  part 
  an 
  opening 
  into 
  the 
  interior 
  both 
  before 
  and 
  behind 
  — 
  thus 
  

   serving 
  both 
  for 
  shelter 
  and 
  food 
  until 
  almost 
  devoured, 
  when 
  it 
  selects 
  a 
  fresh 
  

   leaf, 
  and 
  proceeds 
  with 
  it 
  in 
  the 
  same 
  manner 
  ; 
  one 
  caterpillar 
  only 
  being 
  found 
  

   on 
  a 
  single 
  leaf 
  — 
  thus 
  indicating 
  a 
  peculiar 
  liking 
  for 
  a 
  solitary 
  life'; 
  a 
  circumstance 
  

   confirmed 
  by 
  the 
  eggs 
  being 
  laid 
  solely 
  and 
  apart, 
  whereas 
  caterpillars 
  hatched 
  

   from 
  eggs 
  deposited 
  in 
  clusters 
  are 
  gregarious. 
  The 
  caterpillar 
  state 
  lasts 
  about 
  

   five 
  weeks.
