WHITE   MARKED  TUSSOCK  MOTH   AND 
ELM  LEAF  BEETLE 


BY 
EPHRAIM  PORTER  FELT  D.  Sc. 

These  two  insects  must  be  ranked  among  the  most  important  leaf 
feeders  affecting  the  shade  trees  of  cities  and  villages  in  New  York 
State.  They  were  responsible  during  the  season  of  1906  for  wide- 
spread injury  to  thousands  of  trees,  and  the  experience  of  earlier 
years  shows  that  we  must  reckon  with  these  species  if  we  would 
preserve  the  beauty  of  our  trees.  Both  of  these  pests,  despite  their 
destructiveness,  are  controlled  with  relative  ease.  The  tussock  moth 
can  be  readily  suppressed  in  at  least  two  ways,  while  the  elm  leaf 
beetle  succumbs  quickly  to  timely  applications  of  arsenical  poisons. 
Experience  in  the  past  has  demonstrated  beyond  all  question  the 
practicability  of  checking  both  of  these  leaf  feeders  by  spraying, 
an  operation  which  is  not  very  costly  if  modern  apparatus  be 
employed.  We  are  forced  to  conclude  therefore  that  extensive 
injury  by  either  of  these  pests  must  be  attributed  to  indifference  or 
culpable  neglect  rather  than  inability,  despite  the  fact  that  many 
appear  very  eager  to  take-up  the  warfare  at  a  time  when  the  ravages 
are  most  apparent  and  unfortunately  when  repressive  measures  can 
be  employed  to  very  little  advantage. 

There  is  a  tendency  on  the  part  of  many  private  individuals  to 
attribute  their  woes  to  the  neglect  of  adjacent  shade  trees  on  public 


6  NEW    YORK    STATE    MUSEUM 

streets,  and  conversely  municipal  authorities  are  prone  to  state  that 
injury  to  public  trees  is  due  to  the  pests  swarming  thereto  from 
neglected  private  grounds.  The  facts  of  the  case  are  that  both  of 
these  insects  are  very  local  in  habit.  This  is  a  necessity  in  the  case 
of  the  tussock  moth,  because  the  female  is  wingless  and  as  a  conse- 
quence the  specie's  relies  for  dissemination  on  the  very  limited 
crawling  powers  of  the  caterpillar  or  upon  their  being  carried  by 
other  agencies.  ..The  elm  leaf  beetle,  on  the  contrary,  flies  readily, 
for  s^^^y^sQ-n  or  other  it  is  very  local  in  its  habits  and  not 
55  one  may  see  magnificent  trees  infested  with  hordes  of 
uyafe/vftiile  within  a  block,  sometimes  within  50  feet, 
other  elms  may  be  practically  free  from  the  pest.  These  facts  are 
of  greatest  importance  to  all  interested  in  the  welfare  of  shade  trees, 
since  they  demonstrate  beyond  question  the  possibility  of  protecting 
the  trees  on  our  public  streets,  irrespective  of  what  is  done  by 
private  citizens,  or  conversely,  the  practicability  of  keeping  the  pest 
in  check  on  private  grounds,  even  though  little  or  no  repressive 
work  is  done  upon  those  adjacent. 

White  marked  tussock  moth 
Hemerocampa  leucostigma  Abb.  &  Sm. 

This  insect,  preeminently  a  pest  on  city  and  village  trees,  occa- 
sionally proves  a  veritable  scourge  over  considerable  areas.  Some 
cities  appear  to  be  more  afflicted  in  this  way  than  others.  Buffalo 
seems  to  have  been  specially  unfortunate  in  the  last  six  or  seven 
years.  The  summer  of  1906  was  marked  by  extensive  depredations 
in  a  number  of  cities  and  villages  throughout  the  State,  thus  dupli- 
cating the  experience  of  1898.  It  will  therefore  be  seen  that  serious 
injuries  by  this  caterpillar  are  more  or  less  periodic.  This  is  to  be 
explained  by  the  fact  that  the  species  has  a  number  of  natural 
enemies  which  assist  materially  in  keeping  it  in  subjection.  The 
destructive  outbreaks  are  examples  of  what  might  occur  annually 
were  there  no  parasites  to  check  the  work  of  this  voracious  leaf 
feeder.  The  cause  of  this  native  species  thriving  so  greatly  in  cities 
and  villages  during  recent  years  is  explained  by  the  abundance  of 
the  English  sparrow.  This  bird  will  not  eat  the  caterpillars  and 
drives  away  many  of  the  native  forms  which,  in  earlier  days,  were 
of  great  service  in  devouring  these  hairy  pests. 


WHITE    MARKED    TUSSOCK    MOTH    AND    ELM    LEAF    BEETLE  7 

Description.  The  full  grown  caterpillar  is  really  a  beautiful 
object.  It  has  a  coral  red  head,  a  pair  of  long,  black  plumes  just 
over  it,  a  single  one  at  the  opposite  extremity  of  the  body,  four  deli- 
cate yellowish  or  white,  brushlike  tufts  on  its  back  and  just  behind 
them,  separated  only  by  a  segment,  two  small  retractile  red  eleva- 
tions. There  is  a  broad,  black  band  broken  only  by  tubercles  and 
tufts  along  the  back  and  bordered  by  yellowish  stripes.  Each  side 
is  dark  gray  except  for  the  yellowish  tubercles.  The  breathing 
tubes  or  spiracles  are  in  a  black  line  and  below  this  the  caterpillar 
is  yellow,  the  legs  usually  being  paler  [pi.  i,  fig.  4].  The  very  young 
caterpillar  is  pale  yellowish  or  whitish  with  long,  irregular  hairs.  It 
increases  in  size,  casts  its  skin  from  time  to  time  and  assumes  one 
after  another  the  characteristics  Of  the  full  grown  larva. 

The  thin  cocoons  spun  in  the  crevices  of  the  bark  [pi.  i,  fig.  6] 
have  the  long  hairs  of  the  caterpillar  interwoven  and  within  this 
shelter  the  larva  transforms  to  a  yellowish  white  pupa  more  or  less 
shaded  with  dark  brown  or  black  [pL  i,  fig.  7]. 

The  sexes  differ  strikingly  as  is  shown  on  plate  i,  figures  i  and  2. 
The  male  is  a  beautiful  moth  with  large  feathery  antennae,  tufted 
legs,  and  with  the  wings  and  body  delicately  marked  with  several 
shades  of  gray  or  grayish  white.  The  female,  on  the  other  hand,  is 
a  nearly  uniform  gray  with  simple  antennae  and  but  rudimentary 
wings. 

The  eggs,  usually  over  300,  are  deposited  on  the  empty  cocoon, 
under  a  conspicuous  white  mass  of  frothy  matter  about  ^2  inch  in 
diameter  [pi.  i,  fig.  3].  This  soon  hardens  and  forms  a  very 
effective  protection.  The  egg  masses  [pi.  4,  5]  are  easily  removed 
and  a  tree  thoroughly  cleared  thereof  can  become  infested  again 
only  by  caterpillars  crawling  from  adjacent  trees  or  being  carried 
thereto.  The  individual  egg  is  nearly  spheric,  about  */*$  inch  in 
diameter,  white  or  yellowish  white  and  with  a  light  brown  spot 
surrounded  by  a  ring  of  the  same  color. 

Life  history  and  habits.  This  insect  winters  in  the  conspicuous 
egg  masses  described  above,  the  young  appearing  about  the  latter 
part  of  May  in  this  latitude.  They  feed  at  first  on  the  more  tender 
lower  epidermis  of  the  leaf  and  soon  devour  all  but  the  principal 
veins.  The  caterpillars  while  young  frequently  hang  by  a  silken 
thread  and  continued  jarring  may  cause  many  to  drop  to  the  ground. 
Feeding  and  growth  occupy  a  month  or  more,  pupation  occurring 


8  NEW    YORK    STAT£    MUSEUM 

the  latter  part  of  June  or  early  in  July.  There  is  some  deviation 
from  this,  as  a  few  individuals  spin  up  early  and  some  caterpillars 
linger  till  numerous  egg  clusters  indicate  that  most  of  the  insects 
have  completed  the  round  of  life.  The  pupal  stage  occupies  from 
10  to  15  days.  The  wingless  female  appears  at  the  end  of  this  period, 
crawls  on  her  cocoon  and  shortly  deposits  eggs  as  described.  There 
is  normally  but  one  annual  generation  in  Albany  and  other  inland 
cities,  while  in  New  York  city  and  vicinity  and  in  Boston,  Mass, 
there  are  two  broods  and  at  Washington,  D.  C.  there  are  three 
generations  each  year  as  stated  by  Dr  Howard. 

A  peculiar  habit,  first  recorded  by  the  late  Dr  Lintner  and  subse- 
quently observed  by  us,  is  the  girdling  of  the  elm  twigs  by  larvae  of 
this  insect.  This  is  caused  by  their  eating  a  portion  of  the  bark 
around  the  twig  near  the  beginning  of  the  season's  growth  [pi.  i, 
fig.  8].  The  affected  tips  soon  die,  break  off  and  fall  in  numbers  to 
the  ground.  The  young  caterpillars  drop  from  the  tree  readily,  sus- 
pend themselves  by  silken  threads  and  then  may  be  blown  or  carried 
considerable  distances.  The  full  grown  caterpillars  desert  the  trees 
and  wander  considerably.  This  is  particularly  true  of  the  larger 
ones  which  almost  invariably  produce  female  moths.  The  cocoons 
are  spun  very,  generally  on  the  trunks  or  on  the  underside  of  the 
larger  branches. 

Food  plants.  This  leaf  feeder  exhibits  a  marked  preference  in 
cities  for  the  linden  and  horse-chestnut,  while  it  feeds  readily  on 
elms  and  maples.  It  has  also  been  recorded  on  a  number  of  other 
trees. 

Natural  enemies.  This  species  has  a  number  of  natural  enemies. 
Its  comparative  rarity  in  the  country  shows  that  our  native  birds 
must  be  very  efficient  natural  checks  upon  this  insect.  Mr  E.  H. 
Forbush  states  that  47  species  of  native  birds  feed  on  hairy  cater- 
pillars, most  of  which  would  probably  take  this  leaf  feeder.  The 
robin,  Baltimore  oriole  and  cuckoo  are  among  the  more  valuable  in 
this  respect. 

Paj-asitic  insects  are  also  very  efficient  checks.  This  species  is 
subject  to  attack  by  some  21  primary  parasites  and  these  in  turn 
may  become  the  prey  of  14  hyperparasites. 

Remedies.  A  simple  and  very  satisfactory  method  of  controlling 
this  insect  is  the  gathering  and  destroying  of  egg  masses.  Several 
cities  and  villages  in  New  York  State  have  employed  children  in  this 


WHITE    MARKED    TUSSOCK    MOTH    AND    ELM    LEAF    BEETLE  9 

work  by  offering  a  small  bounty  and  a  system  of  prizes.  The  result 
has  been  that  a  large  number  of  egg  masses  were  secured  and 
destroyed  at  a  comparatively  slight  cost.  The  defect  in  this  method 
is  that  it  is  more  or  less  irregular  in  operation  and  is  usually  resorted 
to  only  after  serious  injury  to  the  trees  has  aroused  public  opinion. 
There  is  no  doubt  as  to  the  effectiveness  of  collecting  egg  masses 
and  in  not  a  few  instances  it  may  prove  the  cheapest  method  of  keep- 
ing this  pest  in  cheek.  It  would  seem  better  for  the  welfare  of  the 
trees  to  make  some  provision  for  the  systematic  collection  of  egg 
masses  from  year  to  year  from  all  the  trees,  even  though  the  cost  be 
somewhat  greater. 

The  collection  of  egg  masses  should  be  supplemented,  if  uncleaned 
trees  are  in  the  vicinity,  by  banding  the  trunks  at  the  time  the  cater- 
pillars begin  to  crawl,  with  some,  material  which  will  prevent  the 
ascent  of  straggling  larvae.  A  very  simple  method  is  to  take  a  band 
of  cotton  batting  some  6  or  8  inches  wide,  wrap  it  around  the  tree, 
tie  a  string  about  its  middle  and  then  turn  the  upper  edge  down  over 
the  string.  Tree  tanglefoot,  a  preparation  made  by  the  same  com- 
pany that  manufactures  tanglefoot  fly  paper,  has  been  used  very 
extensively  on  trees  about  Boston.  It  is  very  adhesive,  remains 
sticky  for  a  considerable  time  and  does  not  injure  the  bark  of  older 
trees  at  least. 

The  tussock  moth  caterpillar  succumbs  readily  to  arsenical  poisons 
and  where  the  trees  are  infested  or  are  likely  to  be  attacked  by  mgre 
than  one  leaf  feeder,  as  is  true  in  the  Hudson  valley,  spraying  is 
perhaps  the  best  method  of  protecting  the  trees.  One  of  the  best 
poisons  for  this  purpose,  particularly  in  sections  infested  by  the  elm 
leaf  beetle,  is  the  prepared  arsenate  of  lead,  a  compound  specially 
manufactured  for  this  purpose.  It  can  be  applied  in  almost  any 
quantities  without  injuring  the  trees  and  is  far  more  adhesive  than 
the  commonly  employed  london  purple,  paris  green  or  other  copper 
arsenites. 

Elm  leaf  beetle 

Galerucella  luteola  Mull. 

This  destructive  beetle,  like  the  white  marked  tussock  moth  dis- 
cussed previously,  is  a  most  dangerous  enemy  to  certain  shade  trees, 
particularly  in  cities.  It  is  in  all  probability  responsible  for  more 
ruined  elms  in  the  Hudson  valley  than  all  other  destructive  agencies 
combined.  It  was  so  exceedingly  abundant  and  injurious  from  1896 


10  NEW    YORK    STATE    MUSEUM 

to  1899  in  the  cities  of  Albany  and  Troy  as  to  literally  compel  some 
action,  or  a  very  large  proportion  of  the  elms  would  have  been 
destroyed.  The  insect  obtained  such  a  start  in  both  of  these  cities 
that  it  was  able  to  destroy  or  ruin  about  1500  elms  in  each  before  the 
end  of  1900.  The  vigorous  measures  employed  both  in  Albany  and 
Troy  have  mitigated  the  plague  very  largely  and  have  demonstrated 
the  practicability  of  keeping  the  insect  in  check.  The  results  in 
both  cities  are  evident  to  any  observer,  because  instead  of  a  large 
proportion  of  the  elms  having  their  leaves  skeletonized  and  browned 
in  midsummer,  as  was  the  rule  in  1896  to  1898,  the  work  of  this  pest 
is  observed  only  here  and  there  and  is  limited  to  sections  where  the 
trees  have  not  been  thoroughly  sprayed  or  to  localities  where  neglect 
is  the  rule.  This  was  very  well  shown  in  the  summer  of  1906  in  both 
Albany  and  Troy.  The  effective  work  of  earlier  years  had  led  many 
to  suppose  that  the  elm  leaf  beetle  was  becoming  less  injurious  and 
consequently  there  was  a  decided  relaxation  in  the  efforts  to  control 
this  insect.  A  very  large  number  of  trees  in  both  cities  suffered 
severely  as  a  result  of  this  partial  cessation  in  control  work. 

Food  plants.  This  leaf  feeder  displays  a  marked  preference  for 
the  more  tender  foliage  of  the  English  and  Scotch  elms,  though  after 
it  has  become  abundant,  it  is  frequently  exceedingly  destructive  to 
the  American  elm.  Its  operations  on  this  latter  tree  have  been 
especially  severe  in  the  city  of  Watervliet. 

Distribution.  This  pest  has  now  attained  an  extensive  distribu- 
tion in  this  country-,  ranging  from  north  of  Salem,  Mass,  to  Char- 
lotte, N.  C.  and  westward  into  Ohio  and  Kentucky.  It  occurs  in 
most  of  the  cities  and  villages  in  the  Hudson  valley,  having  made  its 
way  north  to  Glens  Falls  and  along  the  Mohawk  valley  at  least  to 
Schenectady.  It  has  become  well  established  at  Elmira  and  Ithaca, 
N.  Y.,  and  has  been  known  for  some  years  in  Oswego,  though  it 
does  not  appear  to  have  been  particularly  destructive  in  that  city. 
There  is  no  record  known  to  us  of  this  species  occurring  in  Utica, 
Syracuse,  Rochester  or  Buffalo,  though  it  is  rather  surprising  that  it 
has  not  already  become  established  in  all  of  these  cities. 

Description.  The  skeletonized  brown  appearance  of  the  foliage 
in  midsummer  is  very  characteristic  of  the  work  of  this  pest,  particu- 
larly in  the  eastern  cities  and  villages  of  the  State.  The  irregular, 
oval  holes  about  %  inch  in  diameter,  eaten  by  the  beetles  in  early 
spring,  are  another  indication  of  the  work  of  this  species. 


WHITE    MARKED    TUSSOCK   MOTH    AND   ELM    LEAF   BEETLE  II 

The  parent  beetle  may  be  recognized  by  reference  to  the  colored 
illustration  [pi.  2,  fig.  5,  6].  It  is  about  ^  inch  long,  with  the  head, 
thorax  and  margin  of  the  wing  covers  a  reddish  yellow.  The  coal- 
black  eyes  and  median  spot  of  the  samt,  color  on  the  head  are  promi- 
nent. The  thorax  is  marked  with  a  dorsal  black  spot  of  variable 
shape  and  with  a  pair  of  lateral  ovoid  ones.  The  median  black  line 
on  the  wing  covers  is  widely  separated  from  lateral  stripes  of  the 
same  color  by  greenish  yellow.  The  wing  covers  are  minutely  and 
irregularly  punctured,  bear  a  fine  pubescence  and  at  the  base  of  each 
there  is  an  elongated,  black  spot  in  the  middle  of  the  greenish 
yellow  stripe.  These  markings  are  fairly  constant  in  the  beetle, 
though  the  color  is  quite  variable  during  life  and  changes  more  or 
less  after  death.  Many  of  the  insects  emerging  from  winter  quarters 
have  the  yellowish  stripes  of  the  wing  covers  nearly  obliterated,  by 
black. 

The  orange-yellow  eggs  [pi.  2,  fig.  i]  are  usually  deposited  in 
irregular  rows  side  by  side,  forming  clusters  of  from  3  to  26  or  more 
on  the  underside  of  the  leaf.  Each  egg  is  somewhat  fusiform, 
attached  vertically  by  its  larger  end  and  with  the  free  extremity 
tapering  to  a  paler  rounded  point. 

The  recently  hatched  grub  [pi.  2,  fig.  2]  is  about  »/*>  inch  long 
with  the  head,  thoracic  shield,  numerous  tubercles,  hairs  and  legs 
jet-black.  The  skin  is  dark  yellow  but  the  tubercles  are  so  large  and 
the  hairs  so  prominent  that  the  prevailing  color  of  the  grub  at  this 
stage  is  nearly  black.  An  increase  in  size,  following  molts,  is  accom- 
panied by  the  stiff  hairs  becoming  less  conspicuous  and  the  yellow 
more  prominent,  till  the  grub  becomes  full  grown  [pi.  2,  fig.  3].  It 
is  then  about  12  inch  long,  more  flattened  than  in  the  earlier  stages, 
with  a  broad,  yellowish  stripe  down  the  middle  of  the  back  and  with 
a  narrower  stripe  of  the  same  color  on  each  side,  these  being  sepa- 
rated by  broad,  dark  bands  thickly  set  with  tubercles  bearing  short, 
dark  colored  hairs.  The  dorsal  yellow  stripe  is  broken  on  each  side 
by  a  subdorsal  row  of  black  tubercles  which  decrease  in  size  pos- 
teriorly. The  lateral  yellow  stripe  includes  a  row  of  prominent 
tubercles  with  dark  tips  bearing  hairs  of  the  same  color.  The  under 
surface  is  yellowish. 

The  pupa  [pi.  2,  fig.  4]  is  a  bright  orange-yellow,  about  1  5  inch 
long  and  with  a  very  convex  dorsal  surface  which  bears  transverse 
rows  of  stout,  inconspicuous  hairs.

Life  history.  The  transformations  of  this  insect  are  so  rapid  and 
so  greatly  influenced  by  local  conditions  that  a  man  must  know  what 
to  expect  or  he  will  accomplish  very  little  in  fighting  the  pest,  because 
a  substance  effective  against  the  beetles  or  grubs  may  not  kill  the 
pupae  and,  after  the  larvae  have  begun  to  descend,  may  be  of  no 
value.  The  beetles  winter  in  attics,  sheds,  outhouses  and  other 
shelters.  They  emerge  with  the  advent  of  warm  weather  and  may 
then  be  found  on  the  walks  during  the  sunny  portion  of  the  day  or 
at  the  windows  of  houses,  trying  to  escape.  The  last  of  April  or 
early  in  May,  with  the  appearance  of  the  foliage,  the  beetles  fly  to 
the  elms  and  eat  irregular  holes  in  the  leaves.  Some  time  is  occu- 
pied in  feeding  before  the  deposition  of  eggs,  a  process  which  may 
continue  four  and  possibly  five  or  six  weeks.  The  prolific  beetles 
consume  a  large  amount  of  foliage  during  this  time,  depositing 
clusters  of  from  3  to  26  or  more  eggs  every  day  or  two.  Over  half 
the  total  number  of  eggs  may  be  laid  at  the  hight  of  the  season 
within  about  12  days;  in  1898,  from  June  12  to  23.  A  female  may 
produce  over  600  eggs. 

The  young  grubs  appear  early  in  June  or  about  five  or  six  days 
after  the  eggs  have  been  deposited  later  in  the  season.  They  feed 
on  the  under  surface  of  the  leaf,  producing  the  familiar  skeletoniza- 
tion  [pi.  2,  fig.  7]  which  fs  caused  by  their  eating  the  softer  under- 
part,  leaving  the  veins  and  the  upper  epidermis  practically 
untouched.  The  results  of  their  feeding  are  so  marked  that  it  is 
easy  to  detect  the  presence  of  the  grubs  by  the  semitransparent 
patches  in  the  foliage.  These  latter  soon  dry  and  turn  brown. 

There  are  two  and  occasionally  three  generations  of  this  destruc- 
tive insect  in  the  latitude  of  Albany,  the  number  depending  to  a 
considerable  extent  upon  the  availability  of  suitable  food.  The 
grubs  complete  their  growth  in  from  15  to  20  days,  descending  limbs 
and  trunk  to  a  great  extent  in  search  of  some  shelter  under  which 
to  pupate.  Seven  days  are  spent  in  this  latter  state  in  warm  July 
weather,  while  in  September  it  is  extended  to  12  and  in  October  to 
24  days.  The  grubs  of  the  first  brood  usually  forsake  the  trees  in 
Albany  by  the  last  of  June  or  early  in  July,  and  beetles  belonging  to 
the  second  generation  may  begin  depositing  eggs  about  the  middle 
of  July,  and  from  then  to  late  in  autumn  it  is  generally  possible  to 
find  this  insect  in  all  stages  in  some  part  of  Albany.  The  beetles  of 
the  second  brood  are  naturally  attracted  to  fresh  foliage  and  conse- 


WHITE   MARKED    TUSSOCK    MOTH    AND    ELM    LEAF    BEETLE  13 

quently  more  eggs  are  usually  deposited  on  trees  which  have  been 
defoliated  earlier  in  the  season  than  upon  others. 

Badly  infested  trees  are  therefore  very  likely  to  lose  two  crops  of 
leaves  in  a  season  and  may  possibly  have  their  third  seriously  marred 
by  this  pest.  The  second  brood  of  grubs  completes  its  growth 
about  the  middle  of  August,  beetles  appearing  the  latter  part  of  the 
month,  and  if  there  is  an  abundant  supply  of  fresh  leaves,  a  third 
generation  may  appear  in  considerable  numbers.  This  last  brood 
more  frequently  occurs  in  near-by  trees  which  have  not  been 
severely  injured  earlier  in  the  season. 

Natural  enemies.  This  leaf  feeder  is  subject  to  attack  by  a 
number  of  natural  enemies,  most  of  which,  however,  are  of  compara- 
tively little  importance  in  keeping  it  in  check.  The  common  garden 
toad  will  devour  many  beetles,  and  the  much  despised  English 
sparrow  also  feeds  upon  these  insects  to  some  extent.  Several 
predaceous  insects  prey  upon  this  pest  to  a  certain  degree. 

Remedial  measures.  The  secret  in  controlling  this  insect  lies 
in  understanding  thoroughly  its  life  history  and  appreciating  the 
vulnerable  points.  A  thorough  spraying  with  an  arsenical  poison 
early  in  the  spring,  when  the  beetles  begin  to  feed,  is  most  effective 
in  preventing  breeding,  as  the  parent  insects  are  destroyed  before 
they  can  deposit  many  eggs.  Fortunately  the  beetles  are  rather 
local  in  habit  and  as  a  consequence  individual  trees  or  groups  of 
trees  may  be  protected  to  a  very  large  extent  even  if  there  are  neg- 
lected ones  in  the  near  vicinity.  The  local  spread  of  this  pest  is 
slow  and  this  should  be  taken  advantage  of  to  the  greatest  possible 
extent  by  keeping  the  insect  in  control  wherever  it  occurs,  even 
though  the  infestation  be  a  small  one  and  the  present  injury  of  com- 
paratively little  importance.  It  is  a  mistake  on  the  part  of  local 
authorities  to  wait  till  this  enemy  of  the  elms  has  become  well  estab- 
lished and  destructive  before  repressive  measures  are  undertaken. 

The  grubs  feed  almost  exclusively  on  the  under  surface  of  the 
leaf,  rarely  occurring  upon  its  upper  side.  The  first  injury  is  usually 
on  the  upper  more  tender  leaves,  hence  there  is  great  need  of  spray- 
ing the  tops  of  the  trees,  and  in  order  to  kill  the  destructive  grubs  it 
is  essential  that  the  poison  be  thrown  on  the  underside  of  the  foliage. 
Spraying  with  an  arsenical  poison  for  the  destruction  of  grubs  is 
satisfactory  only  when  the  application  is  early,  as  it  is  hardly  advis- 
able to  spray  for  this  insect  when  the  grubs  are  nearly  full  grown, 


14  NEW    YORK    STATE    MUSEUM 

since  they  are  liable  to  desert  the  tree  even  when  slightly  underfed 
and  complete  their  transformations,  rather  than  to  eat  distasteful 
foliage. 

The  full  grown  larvae  crawl  down  the  trunks  in  great  numbers 
and  the  golden  yellow  pupae  may  be  found  in  abundance  in  crevices 
in  the  bark  and  on  the  ground  about  the  tree.  A  great  proportion 
of  the  insects  can  be  forced  to  take  refuge  on  the  ground  by  scrap- 
ing off  the  rough  bark,  thus  depriving  them  of  shelters  upon  the 
tree.  Large  numbers  can  then  be  killed  when  assembled  about  the 
base  of  the  tree  by  spraying  them  with  a  contact  insecticide  such  as 
kerosene  emulsion,  whale  oil  soap  solution  or  even  by  pouring  boil- 
ing water  on  them.  The  grubs  should  be  destroyed  in  the  manner 
indicated  every  five  days  so  long  as  the  pests  are  seen  in  numbers, 
in  order  to  secure  the  best  results.  This  method  of  fighting  the  pest 
is  advisable  only  when  it  is  impossible  to  employ  the  more  satisfac- 
tory arsenical  sprays.  Bands  of  tar,  sticky  fly  paper,  cotton  batting 
etc.,  while  they  do  no  harm,  can  not  be  considered  of  much  value  in 
keeping  the  elm  leaf  beetle  under  control.  The  relatively  few  grubs 
caught  on  a  sticky  band  are  but  a  drop  in  the  bucket  compared  with 
the  masses  which  complete  their  transformations  either  above  or 
below.  It  is  worse  than  useless  to  attempt  to  control  this  or  any 
other  insect  by  boring  a  hole  in  the  trunk  of  a  tree  and  inserting 
therein  compounds  of  any  nature.  The  tree  is  weakened  and  unless 
the  chemical  be  powerful  enough  to  kill  it,  the  insects  are  not 
affected.
