  Loose-jointed, 
  ungainly 
  flies 
  of 
  moderate 
  size, 
  with 
  long, 
  stout 
  legs, 
  

   body 
  often 
  clothed 
  with 
  long 
  hair, 
  antennae 
  many 
  jointed 
  but 
  short 
  and 
  

   stout, 
  mouth 
  parts 
  a 
  little 
  produced. 
  There 
  is 
  often 
  considerable 
  differ- 
  

   ence 
  between 
  the 
  sexes, 
  and 
  in 
  some 
  cases 
  the 
  females 
  have 
  a 
  ridicu- 
  

   lously 
  small 
  head. 
  From 
  the 
  very 
  early 
  appearance 
  of 
  some 
  species 
  

   they 
  are 
  called 
  "March 
  flies," 
  and 
  sometimes 
  they 
  occur 
  in 
  orchards 
  in 
  

   numbers 
  so 
  great 
  as 
  to 
  attract 
  attention. 
  

  

  The 
  larvae 
  are 
  cylindrical, 
  footless 
  grubs, 
  and 
  "feed 
  on 
  excremental 
  or 
  

   vegetable 
  substances, 
  especially 
  on 
  the 
  roots 
  of 
  grass." 
  They 
  have 
  not 
  

   been, 
  thus 
  far, 
  injurious 
  in 
  New 
  Jersey.
