  Anax 
  Junius 
  Drury 
  

  

  This 
  well 
  knov/n 
  species, 
  which 
  is 
  very 
  common 
  in 
  most 
  parts 
  of 
  the 
  

   state, 
  was 
  rather 
  rare 
  at 
  Saranac 
  Inn. 
  A 
  single 
  nymph 
  was 
  taken 
  from 
  

   the 
  little 
  bog 
  pond 
  on 
  the 
  inn 
  wagon 
  road, 
  

   and 
  a 
  single 
  male 
  imago 
  was 
  observed 
  fly- 
  

   ing 
  over 
  the 
  same 
  pond. 
  Elsewhere 
  the 
  

   imagos 
  are 
  on 
  the 
  wing 
  from 
  March 
  till 
  

   November; 
  they 
  fly 
  from 
  daylight 
  to 
  

   dark, 
  and 
  are 
  fleet, 
  powerful 
  and 
  fearless. 
  

  

  The 
  female 
  in 
  ovipositing 
  is 
  often 
  held 
  

   by 
  the 
  male, 
  specially 
  in 
  early 
  spring, 
  

   often 
  is 
  unattended, 
  and 
  sometimes 
  de- 
  

   scends 
  bodily 
  into 
  the 
  water. 
  In 
  early 
  

   spring 
  the 
  eggs 
  are 
  inserted 
  in 
  the 
  water- 
  

   soaked 
  stems 
  of 
  reeds, 
  in 
  floating 
  sticks, 
  

   etc. 
  ; 
  later 
  in 
  the 
  season 
  they 
  are 
  placed 
  

   in 
  the 
  tissues 
  of 
  green 
  and 
  growing 
  

  

  aquatic 
  plants.

  It 
  is 
  sure 
  to 
  get 
  into 
  the 
  net 
  of 
  the 
  aquatic 
  collector. 
  It 
  clings 
  to 
  

   water 
  weeds 
  nearer 
  the 
  surface, 
  usually, 
  than 
  the 
  bottom, 
  in 
  an 
  atti- 
  

   tude 
  of 
  alertness, 
  with 
  head 
  poised 
  low 
  and 
  abdomen 
  slightly 
  elevated. 
  

   Locomotion 
  is 
  relatively 
  rapid, 
  either 
  by 
  walking, 
  or 
  by 
  swimming 
  by 
  

   ejections 
  of 
  water 
  from 
  the 
  respiratory 
  chamber. 
  It 
  is 
  a 
  notoriously 
  can- 
  

   nibalistic 
  species 
  : 
  among 
  abundant 
  and 
  choice 
  food, 
  the 
  larger 
  nymphs 
  

   will 
  eat 
  the 
  smaller 
  ones, 
  and 
  two 
  of 
  equal 
  size 
  can 
  not 
  be 
  safely 
  kept 
  to- 
  

   gether 
  in 
  close 
  quarters.
