bugs "), are predaceous. Other forms, commonly called 

 borers, are such, as the apple-tree borer, the pine-tree 

 borer (Fig. 163), and the cottonwood borer, the larva of 

 which live within the trees named. There are likewise 



forms which feed upon 



leaves, such as the potato 

 beetle and June beetle. A 

 few abnormal species are 

 parasitic upon bees and 

 wasps. Those whitish FlG 164 A Bnout beetle (9phmopho . 

 grubs found when spading, rus *)-twice natural size, 

 or when in quest of angleworms, belong to the June- 

 beetle family. The eggs from which they emerge are 

 laid beneath the surface of the ground, to hatch within 

 a month to feed upon tender rootlets, or decayed vege- 

 table matter. In autiimn they hibernate below frost 

 line ; in May they pupate near the surface ; in June 

 they emerge. 



The familiar ladybird larvae are for the most part 

 predaceous, feeding upon other insects, especially plant- 

 lice and scale insects ; consequently the black or spotted 

 lame are to be found running around upon plants and 

 trees. (Fig. 107.) Pupation takes place with the pupa 

 pending by the abdomen from leaves, fences, or trunks 

 of trees. 



LEPIDOPTERA. 



These are insects which have long been the recipients 

 of popular attention. They possess haustellate mouth- 

 parts, which take the form of a spirally rolled proboscis, 

 four wings, similar in structure, and covered with 

 minute scales. The metamorphosis is complete. The
