  Family 
  PYRALID^. 
  

  

  This 
  consists 
  of 
  a 
  large 
  number 
  of 
  moderate-sized 
  or 
  small 
  moths 
  

   varying 
  greatly 
  in 
  appearance, 
  and 
  having 
  no 
  one 
  superficial 
  character 
  

   that 
  makes 
  them 
  always 
  recognizable. 
  Structurally 
  they 
  agree 
  in 
  having 
  

   the 
  secondaries 
  with 
  three 
  free 
  inner 
  veins 
  the 
  costal 
  and 
  sub-costal 
  

   united 
  for 
  a 
  short 
  distance. 
  The 
  sub-families 
  are 
  as 
  a 
  rule 
  more 
  easily 
  

   recognizable 
  and 
  have 
  characters 
  that 
  make 
  the 
  bulk 
  of 
  the 
  species 
  

   placeable 
  almost 
  at 
  sight. 
  

  

  The 
  "Pyraustinge" 
  have 
  rather 
  thinly 
  scaled 
  wings, 
  the 
  primaries 
  

   pointed, 
  secondaries 
  never 
  larger 
  and 
  sometimes 
  very 
  small. 
  The 
  colors 
  

   are 
  predominatingly 
  yellowish 
  and 
  whitish 
  with 
  deeper 
  yellow 
  or 
  almost 
  

   transparent 
  markings. 
  Sometimes 
  they 
  are 
  contrastingly 
  white 
  and 
  

   black 
  and 
  a 
  few 
  are 
  red, 
  brown 
  or 
  of 
  other 
  shades. 
  The 
  body 
  is 
  as 
  a 
  

   rule 
  slender, 
  abdomen 
  very 
  long, 
  head 
  distinct, 
  antennae 
  slender, 
  in 
  the 
  

   males 
  sometimes 
  knotted 
  or 
  thickened. 
  The 
  larvae 
  are 
  nearly 
  always 
  

   green 
  with 
  pale 
  stripes 
  and 
  spots 
  or 
  without 
  any 
  markings 
  at 
  all. 
  The 
  

   head, 
  a 
  shield 
  on 
  the 
  dorsum 
  of 
  the 
  first 
  thoracic 
  segment 
  and 
  some- 
  

   times 
  the 
  tubercles 
  are 
  shining 
  black 
  or 
  yellow. 
  They 
  live 
  usually 
  in 
  

   webs 
  or 
  tents, 
  and 
  may 
  be 
  solitary, 
  as 
  is 
  the 
  rule, 
  or 
  social. 
  

  

  The 
  "Nymphulinae" 
  are 
  similar 
  but 
  smaller, 
  more 
  brightly 
  colored 
  

   species 
  with 
  a 
  tendency 
  to 
  narrower 
  wings 
  and 
  angulated 
  primaries. 
  

   The 
  larvae 
  tend 
  to 
  feed 
  on 
  water 
  plants, 
  and 
  some 
  of 
  them 
  are 
  really 
  

   semi-aquatic 
  in 
  habit. 
  

  

  The 
  "Scopariinae" 
  are 
  broader 
  winged, 
  dull 
  ashen 
  gray 
  or 
  blackish 
  

   species 
  with 
  broader 
  secondaries 
  and 
  raised 
  scales 
  in 
  the 
  primaries, 
  

   especially 
  in 
  the 
  males. 
  

  

  The 
  "Pyralinae" 
  vary 
  more 
  than 
  the 
  preceding 
  in 
  color 
  and 
  in 
  wing 
  

   form. 
  But 
  as 
  a 
  rule 
  the 
  primaries 
  are 
  trigonate 
  with 
  reddish 
  or 
  brown 
  

   colors, 
  the 
  secondaries 
  proportionate, 
  tending 
  to 
  continue 
  the 
  markings 
  

   of 
  the 
  primaries. 
  Some, 
  however, 
  have 
  the 
  fore-wings 
  broad 
  and 
  shoul- 
  

   dered, 
  almost 
  like 
  the 
  Tortricidge. 
  In 
  this 
  family 
  we 
  have 
  the 
  hay 
  worms 
  

   and 
  other 
  web-worms 
  attacking 
  stored 
  products. 
  It 
  contains 
  proportion- 
  

   ately 
  more 
  troublesome 
  species 
  than 
  any 
  of 
  the 
  other 
  sub-families, 
  

   although 
  none 
  are 
  destructive 
  to 
  growing 
  vegetation. 
  

  

  The 
  "Chrysauginse" 
  contain 
  gray 
  and 
  blackish 
  species, 
  the 
  primaries 
  

   more 
  or 
  less 
  shouldered, 
  the 
  secondaries 
  usually 
  without 
  markings 
  and 
  

   broader 
  than 
  primaries. 
  There 
  are 
  no 
  injurious 
  species.
