  prefer 
  the 
  more 
  permanent 
  bodies 
  of 
  water, 
  but 
  they 
  are 
  occasionally 
  

   found 
  in 
  puddles 
  and 
  rarely 
  in

  and 
  adults 
  emerged 
  the

  C. 
  melanurus

  The 
  larvae 
  breed 
  and 
  winter 
  in 
  cold 
  spring 
  pools 
  in 
  

   Sphagnum 
  swamps, 
  among 
  the 
  bottom 
  material. 
  They 
  have 
  also 
  

   been 
  found 
  in 
  early 
  August 
  with 
  the 
  egg 
  boat 
  and 
  may 
  breed 
  all 
  

   summer. 
  Thus 
  far 
  found 
  only 
  at

  C.

  Local 
  throughout 
  the

  com- 
  

   mon. 
  Adults 
  appear 
  in 
  May 
  and 
  continue 
  into 
  September. 
  Eggs 
  are 
  

   laid 
  in 
  rafts 
  in 
  overgrown 
  swamps, 
  and 
  the 
  larvae 
  work 
  into 
  the 
  bot- 
  

   tom 
  mud, 
  attach 
  themselves 
  to 
  grass 
  roots, 
  and 
  there 
  remain 
  until 
  

   the 
  following 
  year. 
  Larval 
  growth 
  is 
  very 
  slow, 
  and 
  the 
  adult 
  is 
  very 
  

   long 
  lived 
  and 
  a 
  fierce 
  biter. 
  It 
  comes 
  freely 
  to 
  porches, 
  and 
  is 
  not 
  

   backward 
  in 
  entering 
  houses, 
  making 
  it 
  locally 
  a 
  first-class 
  pest.

   vegetation, 
  the

  laid

  W. 
  smithii 
  Coq. 
  Breeds 
  in 
  the 
  leaves 
  of 
  pitcher 
  plants, 
  "Sarracenia," 
  

   wherever 
  these 
  occur 
  in 
  the 
  State. 
  The 
  adult 
  is 
  a 
  small 
  insect 
  that 
  

   does 
  not 
  bite 
  and 
  lays 
  its 
  eggs 
  in 
  the 
  leaves, 
  fastened 
  to 
  the 
  sides 
  

   when 
  they 
  have 
  no 
  water, 
  or 
  on 
  the 
  surface 
  when 
  they 
  are 
  full. 
  

   Larvae 
  may 
  be 
  found 
  at 
  all 
  times 
  of 
  the 
  year, 
  the 
  winter 
  being 
  passed 
  

   in 
  that 
  stage, 
  sometimes 
  active, 
  in 
  mild 
  weather, 
  sometimes 
  frozen 
  

   solid. 
  The 
  first 
  adults 
  mature 
  late 
  in 
  May. 
  

  

  Family 
  CORETHRID^. 
  

  

  The 
  members 
  of 
  this 
  family 
  have 
  until 
  recently 
  been 
  included 
  with 
  the 
  

   mosquitoes; 
  but 
  in 
  their 
  light 
  colors 
  and 
  generally 
  weak 
  appearance 
  they 
  

   come 
  nearer 
  to 
  the 
  "Chironomidge." 
  The' 
  mouth 
  parts 
  are 
  not 
  extended, 
  

   and 
  are 
  not 
  furnished 
  with 
  lancets, 
  so 
  that 
  they 
  cannot 
  bite. 
  Except 
  in 
  

   the 
  genus 
  "Corethrella" 
  the 
  known 
  larvae 
  of 
  our 
  species 
  are 
  not 
  depend- 
  

   ent 
  upon 
  atmospheric 
  air. 
  They 
  live 
  in 
  the 
  water, 
  maintaining 
  a 
  hori- 
  

   zontal 
  position 
  some 
  distance 
  below 
  the 
  surface, 
  and 
  are 
  so 
  transparent 
  

   as 
  to 
  be 
  almost 
  invisible. 
  They 
  are 
  predatory 
  in 
  habit.
