There are many differentfamilies in this suborder, a large propor-tion of which are protected from beingeaten by birds by their disagreeable odor, which is doubtlessthe accompaniment of an equally disagreeable taste. The other suborder of the Hemiptera—called the Homop-tera—includes several important families of noxious insects,the members of which, fortunately, enter largely into the foodof birds. The most notable of these families are those of theleaf-hoppers and the plant-lice. The leaf-hoppers of the family Jassidce are very oftenfound in the stomachs of birds. These insects are small.
