﻿REPORT 
  OF 
  NEW 
  JERSEY 
  STATE 
  MUSEUM. 
  

  

  Family 
  CICADID^. 
  

  

  Contains 
  the 
  largest 
  species 
  in 
  this 
  

   sub-order, 
  popularly 
  known 
  as 
  "har- 
  

   vest 
  flies," 
  and 
  incorrectly 
  as 
  

   "locusts." 
  They 
  are 
  found 
  on 
  shrubs 
  

   and 
  trees, 
  the 
  males 
  making 
  a 
  shrill- 
  

   ing 
  sound 
  during 
  the 
  daj 
  . 
  This 
  song 
  

   or 
  call 
  is 
  very 
  loud 
  and 
  piercing, 
  and 
  

   is 
  different 
  for 
  each 
  species, 
  so 
  that 
  

   each 
  may 
  be 
  recognized 
  by 
  this 
  char- 
  

   acter 
  alone. 
  In 
  the 
  adult 
  stage 
  they 
  

   feed 
  little 
  or 
  not 
  at 
  all, 
  and 
  are 
  in 
  no 
  

   sense 
  injurious 
  except 
  through 
  their 
  

   method 
  of 
  laying 
  eggs 
  in 
  twigs 
  and 
  

   shoots, 
  and 
  even 
  in 
  this 
  point 
  only 
  the 
  

   "periodical 
  cicada" 
  offends. 
  

  

  The 
  larvae 
  live 
  underground 
  and 
  

   suck 
  the 
  juices 
  of 
  tree 
  and 
  other 
  plant 
  

   roots, 
  but 
  grow 
  so 
  slowly 
  that 
  they 
  

   do 
  no 
  appreciable 
  harm. 
  Just 
  how 
  

   long 
  our 
  common 
  species 
  require 
  for 
  

   their 
  complete 
  life 
  cycle 
  is 
  not 
  defi- 
  

   nitely 
  known; 
  but 
  the 
  larva 
  of 
  the 
  

   "periodical" 
  species 
  is 
  known 
  to 
  live 
  

   in 
  that 
  stage 
  sixteen 
  years 
  in 
  the 
  

   north 
  and 
  thirteen 
  years 
  in 
  the 
  more 
  

   southern 
  States.

  Say. 
  Occurs 
  in 
  June 
  

   and 
  July 
  throughout 
  the 
  pine 
  

   barrens, 
  and 
  is 
  specifically 
  re- 
  

   ported 
  from 
  Lakewood, 
  Lakehurst, 
  

   Lahaway, 
  DaCosta, 
  Anglesea. 
  It 
  

   is 
  the 
  smallest 
  of 
  our 
  species, 
  the 
  

   abdomen 
  is 
  almost 
  transparent, 
  and 
  I 
  have 
  noted 
  it 
  ovipositing 
  in 
  

   cedar.

  T. 
  septendecim 
  Linn. 
  The 
  "periodical 
  cicada" 
  or 
  "17-year 
  locust." 
  

   Occurs 
  at 
  intervals 
  throughout 
  the 
  State, 
  appearing 
  during 
  the 
  last 
  

   days 
  of 
  May 
  and 
  continuing 
  through 
  most 
  of 
  June. 
  There 
  are 
  two 
  

   large 
  broods 
  in 
  the 
  State, 
  a 
  third 
  that 
  is 
  fairly 
  marked 
  and 
  two, 
  if 
  

   not 
  three, 
  that 
  are 
  dying 
  out, 
  and 
  are 
  represented 
  at 
  the 
  present 
  

   time 
  by 
  a 
  few 
  scattered 
  examples 
  only. 
  The 
  adults 
  cause 
  injury 
  

   when 
  they 
  appear 
  by 
  their 
  habit 
  of 
  cutting 
  slits 
  to 
  deposit 
  eggs 
  in 
  

   the 
  terminal 
  twigs 
  of 
  larger 
  trees 
  and 
  in 
  the 
  trunks 
  and 
  branches 
  of
