Excerpt from Practical Beekeeping: Designed for the Use of the Beginner and Small Apiarist, Adapted to the State of Montana

The body Of an insect is divided into three easily distinguish able portions, - the head, the thorax and the abdomen. The origin Or these three divisions can be better understood if a caterpillar be examined. The caterpillar we find is composed of a series Of rings, or metameres, as they are called. The primitive ancestor Of in sects is believed to have had more metameres than insects now possess, and it is supposed that each segment had a pair of appenda ges. In the adult insect of today these rings are more or less unit ed into a varying number in different insects. The head is supposed to be formed Of several Of these segments fused together with the appendages modified to function as mouth parts and sense organs. It is generally agreed that three segments with their three pairs of appendages unite to form the thorax or second section Of the body which bears the three pairs of legs. The remaining segments are usually easily distinguishable even in the adult, though in some instances the last two or three are united and their appendages are modified to aid in the deposition of eggs, or for defense, in the form of a stinger, as is the case in the hornets and bees.
