  Family 
  SYRPHID/E. 
  

  

  These 
  are 
  "flower-flies," 
  usually 
  brightly 
  colored 
  and 
  banded 
  with 
  yel- 
  

   low 
  on 
  a 
  black, 
  bronze 
  or 
  blue 
  ground. 
  They 
  have 
  very 
  short, 
  aristate 
  

   or 
  stylate 
  three-jointed 
  feelers, 
  barrel-shaped 
  bodies, 
  and 
  somwhat 
  flat- 
  

   tened 
  abdomen, 
  varying 
  from 
  slender 
  to 
  broadly 
  oval. 
  Sometimes 
  they 
  

   are 
  almost 
  bare 
  and 
  resemble 
  wasps 
  in 
  appearance 
  and 
  habits; 
  at 
  others 
  

   they 
  are 
  hairy 
  and 
  resemble 
  bees, 
  even 
  in 
  the 
  droning 
  or 
  buzzing 
  noise 
  

   that 
  they 
  make. 
  The 
  mouth 
  parts 
  are 
  formed 
  for 
  scraping 
  and 
  lapping 
  

   only, 
  and 
  they 
  feed 
  upon 
  honey 
  or 
  pollen. 
  

  

  In 
  larval 
  habits 
  they 
  vary 
  greatly. 
  Some 
  are 
  predatory 
  and 
  feed 
  upon 
  

   plant 
  lice; 
  these 
  are 
  usually 
  wrinkled, 
  pointed 
  anteriorly, 
  and 
  live 
  among 
  

   their 
  prey 
  upon 
  leaves 
  of 
  plants. 
  Others 
  feed 
  in 
  

   plant 
  tissue, 
  b.eing 
  more 
  or 
  less 
  maggot 
  or 
  grub- 
  

   like; 
  and 
  yet 
  others 
  are 
  scavengers, 
  the 
  larvae 
  

   feeding 
  in 
  the 
  foulest 
  excrementitious 
  matter; 
  

   these 
  are 
  usually 
  furnished 
  with 
  a 
  long 
  breathing 
  p;^ 
  313.— 
  A 
  "rat-tailed" 
  

   tube 
  from 
  the 
  anal 
  end, 
  and 
  are 
  known 
  as 
  rat- 
  larva. 
  

  

  tailed 
  larvse. 
  Some 
  few 
  species 
  seem 
  to 
  feed 
  

  

  upon 
  pollen, 
  and 
  at 
  least 
  one 
  form 
  occurs 
  between 
  the 
  leaf 
  and 
  stalk 
  

   of 
  corn,- 
  feeding 
  upon 
  the 
  juices. 
  Yet 
  on 
  the 
  whole 
  the 
  species 
  are 
  

   beneficial.
