labrum
A cuticular plate at the front of the insect head, forming an upper lip.
labium The posterior mouthpart of insects. It is often referred to as the "lower lip," is chemosensory, and was derived evolutionarily from paired head appendages (Hexapoda, Arthropoda).
Between the hymen and the frenulum of the labia is the fossa navicularis, while in the groove between the hymen and the labium minus, on either side, the small opening of the greater vestibular (Bartholin's) gland can be seen.
Her maxillae and labium are modified to form a tube through which the food is drawn up into the mouth by the pumping action of the tongue.
mandibles. Used to manipulate solids: e.g., pollen, wax, debris in the hive.
mouthparts consisting of a labrum, a pair of mandibles, a pair of maxillae, a labium, and a tonguelike hypopharynx
