Gardening. 1142. A grub. Larva of a heet](\ H40. Tent-caterpillar. 1141. A maggot. lja-r\'a of n dipterous insect. bees and ants hear sounds too shrill for our ears. In- sects have no true voice, but produce various noises me- chanically, either by rapid movements of their wings, which causes the humming of bees anil flies, or by fric- tion between roughened surfaces on the Ijody or its ap- pendages, thus producing the rasping soujid's or shrill cries of some crickets and grasshoppers. The house-fly hums on F, thus vibrating its wings 335 times in a second, while the wing tone of the honey-bee is A. Usually the males are the musicians of the Insect world, but it is the fe- male of the familiar mosquito which does the singing, and the "biting" also. The male mosquito doubtless hears the song of his mate by means of his antennffi, es the song causes the antennal hairs to vibrate rapidly. Organs which are structurally ear-like have been found in various parts of the body of Insects. The common brown grasshoppers of the fields have a large ear on each side of the first segment of the abdomen; one can easily distinguish with the naked eye the mem- brane or tympanum stretched over a cavity. Many of the long-horned green grasshoppers, katydids and crickets have two similar ears on the tibia of each front leg. Some think that mosquitoes have the faculty of the perception of the direction of sound more highly developed than in any other class of animals. Insects undoubtedly possess the sense of taste.
