ANATOMY OF THE HONEY-BEE 183 



times during the development of the bee. Several 

 moults occur during the larval life: one when the 

 larva changes to a pupa, and the last one when the 

 pupa changes to the adult or winged form, just 

 before leaving the cell in which it has been de- 

 veloped. 



The head. The segments of which the body of an 

 insect is composed are grouped into three regions: 

 the head, the thorax, and the abdomen. 



The head is the first of the three regions. It is 

 formed of several segments grown together so as to 

 from a compact box. It bears the eyes, the antennae, 

 and the mouth-parts. 



The eyes are of two kinds, which are distinguished 

 as the compound eyes and the simple eyes. 



The compound eyes are two in number, one on 

 each side of the head ; they are the organs commonly 

 recognised as the eyes. They are called compound 

 eyes because each consists of a great number of little 

 eyes closely pressed together. If a compound eye 

 be examined with a microscope, it will be seen to 

 present the appearance of a honey-comb, being 

 composed of a great number of six-sided elements; 

 each of these is a separate eye. 



In addition to the compound eyes, the bee has 

 three simple eyes, or ocelli, as they are termed. 

 They are situated on the upper part of the head 

 between the compound eyes. 



The antennae are two slender, many-jointed 

 organs projecting from the front part of the head. 

 Their use has not been fully elucidated. They
