THE HEAD OE THE BEE, 
The eyes of bees are of two kinds, two large 
faceted or compound eyes (Fig. 6, d)^ and three simple 
eyes {ocelli),, of which one only is seen in Fig. 6, i. 
The compound eyes are situated on each side of 
the vertex. They are very large in the drone and 
meet at the top. They are smaller in the queen and 
still smaller in the worker, and in both of these they 
do not meet, but leave exposed a large portion of the

crown. The compound eyes are not found in the larva, 
and yet from the simple organ of this are developed 
the marvellous eyes of the mature insect, with its 
thousands of hexagonal lenses, of which we shall treat 
more fully later. The simple eyes are placed upon 
the vertex in the queen and worker, amongst the 
hairs, and in the drone just below the angle formed by 
the junction of the two compound eyes, and are right 
in front of the face. They are three in number and are 
small, circular protuberances disposed in the form of a 
triangle, one eye at each angle, those of the drone being 
much closer together and nearly touching each other.
