  Habits. 
  — 
  The 
  species 
  is 
  confined 
  very 
  closely 
  to 
  the 
  beds 
  of 
  tansy, 
  

   on 
  which 
  plant 
  the 
  larvae 
  feed 
  ; 
  Sang 
  observes 
  that 
  it 
  is 
  restricted 
  in 
  the 
  

   Darlington 
  district 
  to 
  Tanacetum 
  , 
  although 
  Achillea 
  may 
  be 
  plentiful 
  

   in 
  the 
  same 
  district, 
  to 
  which 
  plant 
  the 
  allied 
  G. 
  pallidactyla 
  [bertrami) 
  

   ishere 
  equally 
  closely 
  confined. 
  Porritt 
  also 
  insists 
  (Ent. 
  Mo. 
  May., 
  xxiiL, 
  

   p. 
  163) 
  on 
  this, 
  observing 
  that, 
  in 
  the 
  Saltburn 
  ravine, 
  also 
  all 
  over 
  

   the 
  district, 
  in 
  August, 
  1886, 
  although 
  yarrow 
  was 
  in 
  full 
  bloom, 
  and 
  

   in 
  equal 
  luxuriance 
  with 
  the 
  tansy, 
  on 
  which 
  he 
  found 
  the 
  species 
  there, 
  

   yet 
  not 
  a 
  single 
  specimen 
  of 
  G. 
  ochrodactyla 
  was 
  seen 
  frequenting 
  it, 
  

   common 
  as 
  it 
  was 
  at 
  the 
  flowers 
  of 
  the 
  Tanacetum. 
  It 
  appears 
  to 
  be 
  

   a 
  very 
  sluggish 
  species 
  during 
  the 
  day, 
  hiding 
  very 
  successfully, 
  and 
  is 
  

   only 
  with 
  difficulty 
  started 
  up 
  from 
  among 
  its 
  foodplant 
  ; 
  it 
  becomes 
  

   active, 
  however, 
  at 
  dusk, 
  when 
  it 
  is 
  found 
  freely 
  at 
  the 
  tansy 
  flowers, 
  

   or 
  flitting 
  about 
  among 
  its 
  foodplant. 
  Bankes 
  observes 
  (in 
  lift.) 
  that 
  

   the 
  species 
  seems 
  very 
  indifferent 
  as 
  to 
  the 
  time 
  of 
  day 
  at 
  which 
  it 
  

   emerges 
  from 
  the 
  pupa 
  ; 
  of 
  the 
  specimens 
  on 
  which 
  careful 
  observations 
  

   were 
  made, 
  thirteen 
  emerged 
  between 
  7 
  a.m. 
  and 
  1 
  p.m., 
  eleven 
  

   between 
  1 
  p.m. 
  and 
  7 
  p.m., 
  seventeen 
  between 
  7 
  p.m. 
  and 
  7 
  a.m., 
  and 
  

   10 
  others 
  between 
  midnight 
  and 
  7 
  a.m. 
  There 
  appears 
  to 
  be 
  no 
  real 
  

   trouble 
  in 
  obtaining 
  pairings 
  of 
  the 
  species 
  in 
  confinement, 
  as 
  both 
  

   Bacot 
  and 
  Bankes 
  obtained 
  them 
  in 
  July, 
  1904. 
  On 
  this 
  point, 
  Bankes 
  

   notes 
  that 
  a 
  $ 
  and 
  a 
  $ 
  that 
  had 
  both 
  emerged 
  early 
  on 
  the 
  morning 
  of 
  

   July 
  15th, 
  1904, 
  were 
  put 
  together 
  into 
  a 
  small 
  cage 
  that 
  day, 
  and 
  

   kept 
  in 
  a 
  warm 
  room 
  ; 
  they 
  did 
  not 
  pair 
  during 
  the 
  night 
  of 
  the 
  15th, 
  

   or 
  day 
  of 
  the 
  16th, 
  but 
  were 
  found 
  in 
  cop. 
  at 
  10.30 
  p.m. 
  on 
  the 
  night 
  

   of 
  the 
  16th, 
  and 
  remained 
  so 
  till 
  between 
  8 
  p.m. 
  and 
  9 
  p.m. 
  on 
  the 
  17th 
  

   (nearly 
  24 
  hours 
  !), 
  when 
  they 
  separated. 
  Bacot 
  observes 
  that, 
  in 
  spite 
  

   of 
  pairings 
  being 
  obtained, 
  it 
  was 
  found 
  impossible 
  to 
  get 
  eggs 
  ; 
  

   the 
  moths 
  lived 
  for 
  some 
  time, 
  waiting 
  apparently 
  for 
  the 
  tansy 
  

   to 
  throw 
  up 
  its 
  flowering 
  stalks 
  to 
  the 
  proper 
  point 
  of 
  develop-
