  p. 
  philenor 
  Linn. 
  Throughout 
  the 
  State, 
  sometimes 
  common; 
  the 
  larva 
  

   on 
  the 
  "Dutchman's 
  pipe," 
  "Aristolochia 
  sipho," 
  which 
  it 
  sometimes 
  

   defoliates 
  completely. 
  There 
  are 
  three 
  broods 
  and 
  specimens 
  occur 
  

   from 
  May 
  to 
  October; 
  one 
  record,

  P. 
  polyxenus 
  Fab. 
  Throughout 
  the 
  State, 
  April 
  to 
  October, 
  and 
  the 
  

   most 
  common 
  of 
  our 
  swallow-tail 
  butterflies. 
  The 
  larvae 
  feed 
  on 
  

   carrot, 
  parsley, 
  celery 
  and 
  similar 
  plants, 
  and 
  are 
  sometimes 
  abund- 
  

   ant 
  enough 
  in 
  gardens 
  to 
  be 
  injurious. 
  Hand-picking 
  is 
  usually 
  the 
  

   most 
  satisfactory 
  method 
  of 
  control, 
  though 
  arsenate 
  of 
  lead 
  is 
  

   effective 
  where 
  it 
  can 
  be 
  safely 
  used.

  A 
  ragged 
  specimen,

   rather

  P. 
  troilus 
  Linn. 
  Not 
  rare 
  throughout 
  the 
  State, 
  April 
  to 
  October, 
  wher- 
  

   ever 
  the 
  food

  occur. 
  Feeds 
  on 
  sassafras, 
  spice-bush 
  and 
  

   "Laurus." 
  

  

  P. 
  turnus 
  Linn. 
  Throughout 
  the 
  State, 
  sometimes 
  common. 
  May 
  to 
  Sep- 
  

   tember. 
  It 
  is 
  the 
  largest 
  of 
  our 
  common 
  butterflies, 
  conspicuous 
  by 
  

   its 
  yellow 
  color 
  and 
  black 
  transverse 
  bands. 
  There 
  is 
  a 
  black 
  

   variety 
  of 
  the 
  female, 
  known 
  as 
  "glaucus," 
  which 
  is 
  rare 
  in 
  New 
  

   Jersey, 
  but 
  more 
  abundant 
  to 
  the 
  south 
  and 
  west. 
  The 
  larva 
  feeds 
  

   on 
  a 
  great 
  variety 
  of 
  orchard 
  and 
  other 
  trees, 
  but 
  is 
  never 
  plentiful 
  

   enough 
  tO' 
  cause 
  injury. 
  

  

  P. 
  thoas 
  Linn. 
  Very 
  occasional 
  throughout 
  the 
  State 
  and 
  even 
  larger 
  

   than 
  the 
  "turnus." 
  Records 
  of 
  actual 
  captures 
  are 
  from 
  Paterson

  (Ds) 
  ; 
  New 
  Brunswick 
  (Sm) 
  ; 
  Trenton 
  (Aaron). 
  The 
  

   larva 
  feeds 
  on 
  orange, 
  prickley 
  ash 
  and 
  hop-tree 
  (Ptella) 
  ; 
  in 
  Florida 
  

   it 
  is 
  known 
  as 
  the 
  "Orange 
  dog." 
  

  

  Family 
  HESPERID/E.. 
  

  

  These 
  are 
  the 
  "skippers," 
  so 
  called 
  because 
  of 
  their 
  low, 
  jerky 
  flight. 
  

   They 
  are 
  usually 
  small, 
  stout 
  butterflies, 
  with 
  tawny, 
  black 
  or 
  smoky 
  

   wings, 
  which 
  may 
  or 
  may 
  not 
  be 
  spotted 
  or 
  marked 
  with 
  black 
  or 
  white. 
  

   The 
  head 
  is 
  broad 
  between 
  the 
  eyes, 
  the 
  antennae 
  are 
  widely 
  separated 
  at 
  

   the 
  point 
  of 
  insertion, 
  their 
  club 
  gradual 
  and 
  pointed, 
  usually 
  a 
  little 
  

   recurved 
  at 
  tip. 
  All 
  the 
  legs 
  are 
  fully 
  developed. 
  At 
  rest 
  these 
  butter- 
  

   flies 
  have 
  the 
  forewings 
  vertical 
  as 
  in 
  the 
  preceding 
  families, 
  but 
  the 
  hind 
  

   wings 
  are 
  held 
  horizontally. 
  

  

  The 
  larvae 
  have 
  large 
  heads, 
  separated 
  by 
  a 
  distinct 
  neck 
  from 
  the 
  rest 
  

   of 
  the 
  body, 
  and 
  they 
  feed 
  mostly 
  on 
  grasses, 
  none 
  of 
  them 
  being 
  of 
  

   economic 
  importance. 
  The 
  pupae 
  are 
  rounded, 
  usually 
  more 
  or 
  less 
  incased 
  

   in 
  a 
  slight 
  cocoon 
  and 
  thus 
  somewhat 
  resembling 
  the 
  moths.
