These worms (Figs. 285, 286 and 287) are very destructive 

 to young plants of various kinds ; their usual mode of pro- 

 cedure is to cut the young plants off and drag them into their 

 burrows, there to devour them at their leisure. Others ascend 

 various kinds of trees and shrubs and feed upon their leaves.

 earthen cell — color, brown. 



They come forth to feed mostly in 

 the night, remaining in their burrows 

 during the daytime. When about to 

 pupate they form smooth cells (Fig. 

 288) in which to undergo their transformations.

 which these grubs (Fig. 290, 2,) hatch, is commonly known as 

 the " May-beetle," or "June-bug.'' It is from eight lines to 

 nearly an inch long, of a nearly uniform chestnut-brown color, 

 and the breast is covered with yellowish hairs.
