The eggs are laid in 

 the earth, and these 

 so o n hatch into 

 small, whitish six-legged grubs, with brownish heads. When 

 at rest they lie upon one side, the body being curved so as to 

 bring the head and tail nearly in contact. They feed upon the 

 roots of various kinds of plants, and are supposed to spend 

 two or three years in this, their larval stage. 



When about to pupate they form smootli oval cells in the 

 earth (Fig. 290, 1,) in which to undergo their transformations. 

 The perfect insects feed upon the leaves of the apple, cherry, 

 and various other fruit and ornamental trees.
