﻿REPORT 
  OF 
  THE

  ENTOMOLOGIST

  allies 
  in 
  fighting 
  an 
  army 
  of 
  these 
  caterpillars. 
  Most, 
  if 
  not 
  all, 
  of 
  the 
  

   insectivorous 
  birds 
  feed 
  readily 
  on 
  them. 
  Some 
  of 
  the 
  most 
  serviceable 
  

   are 
  the 
  bobohuk, 
  blackbird, 
  robin, 
  and 
  meadow 
  lark. 
  The 
  English 
  

   sparrow 
  should 
  be 
  credited 
  with 
  feeding 
  on 
  the 
  army-worm 
  to 
  a 
  certain 
  

   extent. 
  Others 
  that 
  have 
  been 
  observed 
  are 
  the 
  king-bird, 
  blue-jay, 
  

   golden- 
  winged 
  woodpecker, 
  phcebe, 
  cow-bird, 
  Baltimore 
  oriole, 
  chip- 
  

   ping 
  sparrow, 
  chickadee, 
  and 
  quail. 
  Frogs 
  and 
  toads 
  devour 
  them 
  with 
  

   a 
  relish, 
  the 
  remains 
  of 
  as 
  many 
  as 
  fifty-five 
  having 
  been 
  found 
  in 
  the 
  

   stomach 
  of 
  one 
  garden 
  toad. 
  

  

  A 
  number 
  of 
  predaceous 
  insects 
  are 
  known 
  to 
  prey 
  on 
  the 
  caterpillars. 
  

   The 
  more 
  common 
  and 
  perhaps 
  the 
  most 
  important 
  belong 
  to 
  the 
  family 
  

   of 
  CarabidcB, 
  or 
  ground-beetles, 
  which 
  may 
  be 
  found 
  under 
  stones 
  and 
  

   other 
  shelters 
  in 
  the 
  fields. 
  One 
  of 
  the 
  most 
  efficient 
  of 
  these 
  in 
  this 
  

   State, 
  is 
  the 
  fiery 
  ground-beetle, 
  Calosoma 
  calidum 
  (Fabr.). 
  This 
  fine 
  

   beetle 
  may 
  be 
  easily 
  recognized 
  by 
  the 
  six 
  rows 
  of 
  large 
  coppery-red, 
  or 
  

   golden 
  spots 
  on 
  the 
  wing-covers. 
  Both 
  the 
  beetle 
  and 
  its 
  larva, 
  are 
  fierce 
  

   enemies 
  of 
  the 
  ordinary 
  cut-worms, 
  as 
  well 
  as 
  army-worms. 
  In 
  the 
  

   Southern 
  States, 
  the 
  alHed 
  Calosoma 
  scrutator 
  (Fabr.), 
  with 
  its 
  bright 
  

   green 
  wing-covers 
  margined 
  with 
  a 
  resplendent 
  coppery-red, 
  is 
  an 
  equally 
  

   deadly 
  enemy 
  of 
  the 
  army-worm. 
  Two 
  other 
  species 
  of 
  this 
  genus, 
  C. 
  

   externum 
  (Say) 
  and 
  C. 
  Wilcoxi 
  Lee, 
  have 
  also 
  been 
  observed 
  preying 
  on 
  

   the 
  caterpillars. 
  A 
  common 
  tiger-beetle 
  in 
  this 
  State, 
  Cicindela 
  repanda 
  

   Dej., 
  is 
  another 
  of 
  its 
  deadly 
  foes. 
  Besides 
  these, 
  the 
  following 
  ground- 
  

   beetles 
  have 
  been 
  observed 
  preying 
  on 
  the 
  caterpillars 
  : 
  Elaphrus 
  rus- 
  

   carius 
  Say, 
  Pasimachus 
  elongatus 
  Lee, 
  Pterosiichus 
  sculptus 
  Lee, 
  A?fmra 
  

   aiigustata 
  Say, 
  Platynus 
  sinuatus 
  (Dej.), 
  Craiacanthus 
  duhius 
  (Beauv.), 
  

   Harpalus 
  caliginosus 
  (Fabr.), 
  H. 
  Peii/isylvaJiicus 
  (DeGeer), 
  Selenophorus 
  

   pedicularius 
  (Dej.,) 
  and 
  Ajiisodactylus 
  rusticus 
  (Say"). 
  A 
  large 
  southern 
  bug, 
  

   Metapodius 
  femoratus 
  (Fabr.), 
  has 
  been 
  observed 
  in 
  large 
  numbers 
  sucking 
  

   the 
  juices 
  from 
  ihe 
  army- 
  worms. 
  This 
  rapacious 
  insect, 
  it 
  is 
  said, 
  has 
  

   the 
  peculiar 
  habit 
  of 
  hanging 
  the 
  caterpillar 
  skins 
  after 
  it 
  has 
  sucked 
  them 
  

   dry, 
  in 
  the 
  crotches 
  of 
  May-weed 
  in 
  the 
  infested 
  field. 
  

  

  The 
  large 
  ground 
  spiders 
  are 
  said 
  to 
  prey 
  freely 
  on 
  the 
  army-worms, 
  

   and 
  the 
  spinning 
  forms 
  often 
  entrap 
  the 
  moths 
  in 
  their 
  webs 
  for 
  their 
  food. 
  

  

  Parasites. 
  

  

  The 
  army-worm 
  is 
  subject 
  to 
  the 
  attacks 
  of 
  a 
  large 
  number 
  of 
  true 
  

  

  parasites, 
  several 
  of 
  which 
  are 
  very 
  destructive 
  to 
  the 
  caterpillars, 
  and 
  may 
  

  

  be 
  classed 
  with 
  natural 
  enemies, 
  having 
  an 
  important 
  part 
  in 
  keeping 
  the 
  

  

  insect 
  from 
  becoming 
  excessively 
  abundant.

  most 
  important
