  The 
  larger 
  forest 
  tent- 
  

   caterpillars 
  are 
  about 
  one 
  third 
  grown 
  [at 
  Putnam 
  Station], 
  and 
  it 
  looks 
  

   as 
  if 
  they 
  would 
  be 
  very 
  numerous 
  this 
  season.

  — 
  A 
  trip 
  through 
  several 
  

   groves 
  shows 
  that 
  very 
  few 
  forest 
  tent-caterpillars 
  [Clisiocampa 
  

   dis 
  stria] 
  are 
  present, 
  the 
  cold 
  of 
  the 
  past 
  few 
  days 
  possibly 
  having 
  

   some 
  effect.

  An 
  examination 
  of 
  five 
  maple 
  groves 
  leads 
  me 
  

   to 
  beHeve 
  that 
  the 
  caterpillars 
  are 
  the 
  worse 
  for 
  the 
  cold 
  weather, 
  as 
  there 
  

   were 
  many 
  dead 
  ones 
  among 
  the 
  leaves. 
  Branches 
  with 
  the 
  remains 
  of 
  

   the 
  web 
  on 
  the 
  surface 
  or 
  in 
  the 
  axil 
  had 
  no 
  caterpillars 
  or 
  else 
  dead 
  

   ones. 
  Unfortunately 
  some 
  of 
  the 
  eggs 
  had 
  not 
  hatched 
  before 
  the 
  cold 
  

   weather, 
  and 
  they 
  threaten 
  considerable 
  damage, 
  specially 
  in 
  valleys 
  

   where 
  the 
  sun 
  does 
  not 
  strike 
  and 
  vegetation 
  and 
  other 
  life 
  is 
  more 
  back- 
  

   ward. 
  Others 
  in 
  this 
  vicinity 
  think 
  that 
  the 
  cold 
  has 
  checked 
  and 
  possibly 
  

   destroyed 
  a 
  large 
  proportion 
  of 
  the 
  caterpillars. 
  Groves 
  that 
  were 
  en- 
  

   tirely 
  denuded 
  last 
  year 
  are 
  putting 
  forth 
  leaves 
  this 
  spring 
  on 
  about 
  one 
  

   half 
  of 
  the 
  branches. 
  Many 
  of 
  the 
  twigs 
  are 
  dead, 
  and 
  adventitious 
  buds 
  

   are 
  springing 
  from 
  the 
  sides 
  of 
  the 
  branches. 
  Many 
  individual 
  trees 
  are 
  

   entirely 
  dead.

  Dutchess 
  county 
  (H.

  Lewis, 
  Annandale) 
  — 
  The 
  warm 
  weather 
  of 
  

   10 
  days 
  ago 
  has 
  brought 
  out 
  quite 
  a 
  number 
  of 
  tent-caterpillars 
  [Clisio- 
  

   campa 
  americana]. 
  They 
  are 
  less 
  apparent 
  now, 
  possibly 
  because 
  of 
  

   the 
  cold 
  weather. 
  Bud 
  moths 
  [Tmetocera 
  ocellana] 
  are 
  present 
  in 
  

   some 
  numbers, 
  but 
  they 
  have 
  not 
  caused 
  much 
  damage. 
  Many 
  young 
  trees 
  

   in 
  this 
  section 
  are 
  badly 
  infested 
  with 
  the 
  scurfy 
  bark 
  louse 
  [Chion- 
  

   aspis 
  furfur 
  a]. 
  May

  The 
  recent 
  cold 
  weather 
  has 
  greatly 
  reduced 
  

   the 
  number 
  of 
  tent- 
  caterpillars. 
  Many 
  of 
  the 
  nests 
  are 
  smaller 
  than 
  

   usual 
  and 
  contain 
  numbers 
  of 
  dead 
  caterpillars. 
  There 
  was 
  an 
  enormous 
  

   supply 
  to 
  begin 
  with 
  and 
  there 
  still 
  remain 
  a 
  goodly 
  number. 
  This 
  insect 
  

   was 
  probably 
  four 
  times 
  as 
  numerous 
  as 
  last 
  year, 
  and 
  the 
  cold 
  weather 
  

   may 
  have 
  reduced 
  its 
  numbers 
  by 
  one 
  half. 
  There 
  is 
  a 
  large 
  increase 
  in 
  

   the 
  numbers 
  of 
  the 
  forest 
  tent-caterpillars 
  [Clisiocampa 
  disstria] 
  

   which 
  are 
  just 
  appearing. 
  There 
  is 
  a 
  total 
  absence 
  of 
  aphids 
  up 
  to 
  date.

  The 
  estimated 
  reduction 
  of 
  one 
  half 
  in 
  the 
  number 
  of 
  tent- 
  

   caterpillars 
  now 
  appears 
  too 
  high, 
  still 
  many 
  were 
  killed. 
  They 
  are 
  more 
  

   abundant 
  than 
  they 
  have 
  been 
  for 
  20 
  years, 
  with 
  one 
  exception. 
  May 
  

   21. 
  The 
  past 
  three 
  weeks 
  have 
  been 
  pretty 
  fully 
  occupied 
  fighting 
  cater- 
  

   pillars, 
  but 
  that 
  is 
  nearly 
  at 
  an 
  end 
  now. 
  Currant 
  worms 
  [Pteronus 
  

   ribesii] 
  are 
  present 
  in 
  about 
  average 
  numbers.
