family is tin- Colorado potato-beetle, but there are many 

 others, such as the corn-root worm, the various tlca-beetles, 

 the striped cucumber-beetle, and the asparagus-beetle, which 

 ;ire almost equally injurious. The larva? of this group vary 

 much in appearance and life-history: 

 some live exposed on leaves, others 

 are leaf-miners, and others live on 

 roots and under ground. Most of the 

 larva 1 are protected in some way from 

 the attacks of birds, which apparently 

 devour many more of the adult bee- 

 fles than of the larva 1 . 



The common May-beetle, or li June- 

 bug." belongs to a family Scarabttidw 

 which contains many other well- 

 known depredators. This insect is 

 developed from the white grub, or 

 grub-worm." so often found in pasture and meadow land. 

 The rose-beetle, or t% rose-bug," is one of the others : the 

 adult is a hard, brown insect that feeds upon the foliage, 

 flowers, or fruit of a great variety of plants. Its eggs are 

 deposited in light sandy soil and the larvae feed upon roots. 

 When fully grown they change to pupa? and later emerge 

 as adult beetles. Grubs like 1 these are eagerly devoured by 

 robins, blackbirds, crows, and others ; these natural enemies 

 aid greatly in checking the ravages of such pests. 



A large number of injurious insects are found among the 

 snout-beetles of the family Curcnlionidas and certain related 

 families grouped together in a suborder called Rhyncophora. 

 The plum and apple cnrculios. the bean and pea weevils, the 

 various grain weevils, the corn u bill-bug," the white-pine 

 borer, and many other pests belong here. The larva? of these 

 insects are usually footless grubs and feed upon a variety of 

 materials. The adult beetles have a habit when disturbed of 

 dropping to the ground, drawing the legs against the body,
