  Habits. 
  — 
  The 
  moth 
  is 
  very 
  local, 
  yet 
  plentiful 
  in 
  its 
  restricted 
  

   haunts 
  ; 
  it 
  hides 
  during 
  the 
  day 
  among 
  coarse 
  herbage, 
  and 
  especially 
  

   among 
  ragwort 
  in 
  marshy 
  places, 
  and 
  is 
  very 
  sluggish 
  when 
  disturbed, 
  

   shuffling 
  into 
  the 
  nearest 
  hiding-place, 
  but, 
  before 
  dusk, 
  it 
  begins 
  to 
  be 
  

   very 
  lively, 
  flying 
  about 
  such 
  places 
  quite 
  freely 
  ; 
  later, 
  at 
  night, 
  

   ascending 
  to 
  fly 
  abroad 
  over 
  the 
  country, 
  and 
  sometimes 
  even 
  hang 
  

   upon 
  a 
  roadside 
  gaslamp. 
  The 
  females 
  are 
  particularly 
  sluggish 
  

   (Barrett). 
  The 
  moths, 
  during 
  the 
  day, 
  rest 
  among 
  Senecio 
  aquaticus 
  

   or 
  other 
  marsh 
  plants, 
  from 
  which 
  they 
  may 
  be 
  more 
  or 
  less 
  easily 
  

   disturbed. 
  They 
  are 
  on 
  the 
  wing 
  during 
  the 
  evening, 
  until 
  about 
  dusk, 
  

   in 
  favourable 
  weather, 
  flitting 
  to 
  and 
  fro 
  amongst 
  the 
  marsh 
  herbage 
  

   in 
  characteristic 
  Alucitid 
  manner, 
  and 
  with 
  the 
  usual 
  jerky 
  flight. 
  I 
  

   have 
  taken 
  the 
  imago 
  on 
  the 
  wing 
  as 
  early 
  as 
  4.40 
  p.m., 
  in 
  an 
  excep- 
  

   tionally 
  shady 
  spot, 
  on 
  September 
  18th, 
  whereas 
  in 
  June, 
  or 
  early 
  

   August 
  it 
  would, 
  of 
  course, 
  not 
  come 
  on 
  flight 
  until 
  a 
  considerably 
  

   later 
  hour. 
  The 
  $ 
  s 
  are 
  decidedly 
  more 
  lethargic 
  than 
  the<? 
  s 
  (Bankes). 
  

   Griffith 
  notes 
  that 
  he 
  took 
  a 
  fine 
  series 
  in 
  South 
  Uist, 
  flying 
  in 
  the 
  

   evening 
  over 
  a 
  large 
  marsh 
  where 
  half-an-hour 
  earlier 
  Bactra 
  furfurana 
  

   was 
  abundant. 
  Chapman 
  observes 
  that, 
  at 
  Puerto 
  de 
  Pajares, 
  in 
  

   Spain, 
  the 
  imagines 
  were 
  common 
  and 
  easily 
  disturbed 
  from 
  among 
  

   Senecio 
  aquaticus, 
  both 
  in 
  the 
  mornings 
  and 
  evenings. 
  [Evans 
  observes 
  

   (Ami. 
  Scot. 
  Nat. 
  Hist., 
  1897, 
  p. 
  100) 
  having 
  taken 
  a 
  doubtful 
  specimen 
  

   of 
  this 
  species 
  off 
  a 
  lamp 
  at 
  Merchiston 
  in 
  October, 
  1894.]

  at

  one

  the
