﻿THE 
  INSECTS 
  OF 
  NEW 
  JERSEY. 
  8oi 
  

  

  Family 
  TRYPETID^. 
  

  

  The 
  "peacock 
  flies,"' 
  so 
  called 
  because 
  of 
  their 
  habit 
  of 
  elevating 
  the 
  

   wings 
  and 
  strutting 
  about, 
  peacock 
  like. 
  These 
  wings 
  are 
  often 
  prettily- 
  

   marked 
  and 
  spotted 
  with 
  black 
  or 
  brown. 
  In 
  the 
  female 
  the 
  abdomen 
  

   is 
  often 
  prolonged 
  into 
  a 
  horny 
  ovipositor. 
  The 
  flies 
  are 
  gracefully 
  built, 
  

   fly 
  slowly 
  and 
  are 
  noticeable 
  by 
  keeping 
  their 
  wings 
  in 
  constant 
  motion. 
  

   Most 
  of 
  the 
  members 
  of 
  the 
  series 
  feed 
  in 
  plant 
  tissue 
  of 
  some 
  kind, 
  

   either 
  in 
  leaves, 
  in 
  stems 
  or 
  in 
  fruits, 
  and 
  a 
  number 
  of 
  them 
  are 
  gall- 
  

   makers. 
  The 
  only 
  species 
  of 
  economic 
  importance 
  in 
  this 
  State 
  is 
  the 
  

   "Apple 
  maggot," 
  which 
  injures 
  some 
  of 
  the 
  early 
  summer 
  varieties. 
  The 
  

   only 
  remedial 
  measure 
  is 
  the 
  prompt 
  removal 
  and 
  disposal 
  of 
  all 
  fruit 
  

   from 
  trees 
  known 
  to 
  be 
  infested.
