[Feeding upon the roots of barley, corn, turnips, strawber- 

 ries, etc. ; a grayish footless grub, having the hind end of the 

 body apparently cut squarely off and provided with tubercles.] 



Fig. 257. — Crane Fly ; i, the 

 larva or maggot — color, gray ;

 the fly — color, brown ; Jf^ the 

 eggs. 



In England the larva3 (Fig. 

 257, -?,) of these flies are known 

 by the name of " Leather Jack- 

 ets," on account of their tough, 

 leathery skins. In that coun- 

 try they are sometimes very 

 destructive to various crops 

 by feeding upon the roots ; 

 but I am not aware that they 

 have ever been reported as 

 being very injurious in this 

 State, although quite a number of species are found here.
