   stages 
  unknown. 
  

  

  Family 
  CHIRONOMID^. 
  

  

  These 
  flies 
  are 
  indifferently 
  named 
  "gnats," 
  "midges," 
  sand-flies" 
  or 
  

   "punkies," 
  the 
  latter 
  two 
  names 
  chiefly 
  applied 
  to 
  the 
  few 
  minute 
  forms 
  

   with 
  piercing 
  mouth 
  parts. 
  They 
  somewhat 
  resemble 
  mosquitoes 
  in 
  

   appearance, 
  but 
  have 
  naked 
  wings, 
  and 
  the 
  thorax 
  is 
  produced 
  so 
  as 
  to 
  

   hide 
  the 
  small 
  head 
  from 
  above. 
  The 
  antennae 
  in 
  the 
  male 
  are 
  lengthily 
  

   plumose, 
  and 
  in 
  the 
  female 
  are 
  also 
  furnished 
  with 
  lateral 
  hair. 
  The 
  

   insects 
  occur 
  at 
  all 
  seasons, 
  many 
  of 
  them 
  in 
  spring, 
  and 
  they 
  dance 
  in 
  

   the 
  early 
  evening 
  in 
  great 
  swarms 
  only 
  a 
  few 
  feet 
  above 
  ground, 
  usually 
  

   in 
  a 
  damp 
  locality. 
  The 
  larvae 
  live 
  in 
  water 
  on 
  living 
  or 
  dead 
  vegetation, 
  

   or 
  on 
  sap 
  of 
  trees, 
  under 
  fallen 
  leaves 
  or 
  decaying 
  vegetable 
  matter. 
  

  

  As 
  a 
  rule, 
  they 
  are 
  harmless, 
  except 
  for 
  the 
  annoyance 
  caused 
  by 
  the 
  

   biting 
  tribes, 
  but 
  the 
  larva 
  of 
  one 
  species 
  at 
  least 
  mines 
  the 
  leaves 
  of 
  

   water 
  plants, 
  and 
  thus 
  becomes 
  injurious 
  in 
  a 
  very 
  limited 
  and 
  special 
  

   way.
