Mandibular nerve, Motor innervation and proprioceptors of the mouthparts in the worker honey bee Apis mellifera. Maxillolabial structures are modified to form the lapping tongue. Piercing blood-sucking proboscides evolved either from (1) generalized biting-chewing mouthparts, (2) from piercing mouthparts of predators, or plant sap or seed feeders, (3) from lapping or sponging mouthparts. The mandibles of a bull ant European honeybee (Apis mellifera) lapping mouthparts, showing labium and maxillae. honey bee. The mouthparts of bees have been slightly modified to form a long tube and a hairy tongue which is used for sucking up nectar from flowers. But mandibles are blunt and not toothed. Feeding Mechanism: The galeae fit tightly lengthwise, against the elongated labial palps and they in turn roof over the elongated glossae (tongue) to form a temporary food channel through which saliva is discharged. Honey bee). The glossa terminates into a small circular spoon shaped lobe called flabellum, which is useful to lick the nectar. 1.6) .The mouthparts are unfolded and spread apart. Maxillolabial structures are modified to form the lapping tongue. The tongue is extended and immersed into nectar. Lapping is a mode of feeding in which liquid or semi-liquid food adhering to a protrusible organ, or “tongue”, is transferred from substrate to mouth. But mandibles are blunt and not toothed. Ingesting liquid food by bees is based on mechanism of "viscous dipping" [5]. They are useful to crush and shape wax for comb building; ingest pollen grains and other manipulative functions.
