Keshto Patel's Answer
A bee's head is dominated by two large compound eyes. Between the compound eyes are three small ocelli or simple eyes which register light levels.
The antennae sit almost in the center of the face. Each is composed of a basal stalk or scrape and a longer segmented flagellum.
The thorax is the middle portion of the bee's body where the legs and wings are attached. Each pair of legs are specialized in structure for performing different activities. The front legs are used to clean the head, eyes and mouth and also have a special cleaning apparatus for grooming the antennae. The middle pair of legs are used to clean the body, loosen pollen from the pollen baskets, clean the wings and move wax plates that are secreted from glands on the abdomen. The hind legs are specialized for pollen collection. Each leg is flattened, and on workers are covered with long fringed hairs that form the pollen basket.
The abdomen contains the digestive, and reproductive organs of the bee. There are several abdominal segments, each composed of an upper tergum, and a lower sternum with the lower portion overlapping the segment behind it.
At the end of the abdomen is the sting, which when not in use is completely retracted into the abdomen. The sting is made of an upper stylet and two lower lancets.
