  known 
  as 
  wrigglers, 
  live 
  in 
  water, 
  and 
  can 
  develop 
  in 
  water 
  only; 
  but 
  

   the 
  conditions 
  under 
  which 
  the 
  different 
  species 
  live 
  vary 
  greatly. 
  Not 
  

   all 
  the 
  mosquitoes 
  bite 
  human 
  beings 
  and 
  only 
  a 
  few 
  of 
  them 
  follow 
  him 
  

   into 
  his 
  habitation, 
  so 
  that 
  the 
  majority 
  of 
  species 
  are 
  indifferent 
  to 
  the 
  

   great 
  bulk 
  of 
  mankind. 
  But 
  some 
  species 
  are 
  either 
  almost 
  unbearable 
  

   pests, 
  rendering 
  large 
  areas 
  almost 
  uninhabitable, 
  or 
  are 
  actual 
  carriers 
  

   of 
  disease 
  organisms. 
  Destructive 
  methods 
  for 
  the 
  pestiferous 
  species 
  

   are 
  now 
  well 
  understood, 
  and 
  the 
  day 
  of 
  their 
  control 
  is 
  almost 
  at 
  hand. 
  

  

  ANOPHELES 
  Meig. 
  

  

  The 
  members 
  of 
  this 
  genus 
  are 
  intermediate 
  hosts 
  for 
  the 
  organism 
  

   causing 
  malaria 
  in 
  man, 
  though 
  of 
  the 
  species 
  occurring 
  in 
  New 
  Jersey 
  

   only 
  one 
  — 
  "quadrimaculatus"— 
  has 
  been 
  actually 
  convicted 
  of 
  that 
  offense. 
  

   The 
  adults 
  may 
  be 
  known 
  by 
  their 
  method 
  of 
  holding 
  the 
  body 
  at 
  a 
  nearly 
  

   right 
  angle 
  to 
  the 
  plane 
  of 
  the 
  surface 
  upon 
  which 
  they 
  are 
  at 
  rest. 
  The 
  

   eggs 
  are 
  laid 
  singly 
  on 
  the 
  surface 
  of 
  the 
  water 
  and 
  the 
  larva? 
  float 
  on 
  

   the 
  surface, 
  parallel 
  with 
  it. 
  They 
  inhabit 
  pools 
  of 
  ground-water, 
  the 
  

   edges 
  of 
  overgrown 
  swamps 
  or 
  ponds, 
  the 
  quiet 
  eddies 
  of 
  sluggish 
  

   streams 
  and 
  sometimes 
  eA'-en 
  lot-pools, 
  pails, 
  buckets 
  or 
  other 
  receptacles 
  

   containing 
  stagnant 
  water. 
  They 
  are 
  not 
  so 
  abundant 
  in 
  sewage 
  water. 
  

   The 
  adults 
  winter 
  in 
  barns, 
  cellars, 
  hollow 
  trees 
  and 
  similar 
  sheltered 
  

   places, 
  only 
  the 
  females 
  living 
  over. 
  

  

  A. 
  punctipennis 
  Say. 
  Occurs 
  throughout 
  the 
  State, 
  but 
  more 
  commonly 
  

   in 
  the 
  southern 
  portions. 
  Larvae 
  may 
  be 
  found 
  from 
  May 
  to 
  Novem- 
  

   ber; 
  but 
  are 
  usually 
  rare 
  until 
  after 
  midsummer; 
  after 
  mid-Septem- 
  

   ber 
  only 
  stragglers 
  remain. 
  Breeds 
  in 
  almost 
  any 
  waters 
  except 
  on 
  

   salt 
  marshes. 
  

   A. 
  quadrimaculatus 
  Say 
  — 
  maculipennis 
  of 
  American 
  authors. 
  This 
  is 
  the 
  

   species 
  that 
  has 
  been 
  convicted 
  of 
  transmitting 
  malaria. 
  It 
  occurs 
  

   throughout 
  the 
  State, 
  but 
  is 
  rather 
  more 
  common 
  in 
  the 
  northern 
  

   counties. 
  The 
  general 
  habits 
  are 
  like 
  those 
  of 
  the 
  preceding, 
  but 
  

   the 
  larvae 
  occur 
  also 
  in 
  more 
  shaded 
  areas, 
  and 
  occasionally 
  in 
  the 
  

   brackish 
  waters 
  of 
  the 
  salt 
  marshes. 
  

   A. 
  crucians 
  Wied. 
  Occurs 
  chiefly 
  along 
  the 
  coast 
  line 
  from 
  Elizabeth 
  to 
  

   Cape 
  May, 
  more 
  common 
  southwardly, 
  and 
  the 
  larvae 
  breed 
  chiefly 
  

   on 
  the 
  salt 
  marsh 
  or 
  on 
  swampy 
  areas 
  not 
  far 
  inland. 
  The 
  species 
  

   does 
  not 
  become 
  obvious 
  imtil 
  mid-summer 
  and 
  remains 
  until 
  late 
  

   fall. 
  The 
  inland 
  points 
  at 
  which 
  single 
  examples 
  have 
  been 
  taken 
  

   are

  X,

  (Dke), 
  Delair 
  (Seal)

  adults 
  (Brakeley) 
  ;

  larvae 
  (Dn). 
  This 
  species 
  breeds 
  exclusively 
  in 
  the 
  water 
  in 
  

   tree 
  holes 
  and 
  never 
  gets 
  far 
  away 
  from 
  its 
  breeding 
  grounds. 
  

  

  PSOROPHORA

  P. 
  ciliata 
  Fabr. 
  Local 
  throughout 
  the 
  State 
  and 
  rarely 
  common 
  as 
  an 
  

   adult. 
  This 
  is 
  our 
  largest 
  species 
  and 
  lays 
  its 
  eggs 
  in
