Chewing and Lapping Type (e.g. Honey bee)

This type of mouthparts are possessed by Honey bee wherein, the Labrum & Mandibles remain more or less similar as that of the Generalized type, whereas the other components viz. (Maxillae & Labium) are greatly modified Labrum. It is narrow and quite simple.

Mandibles: They are blunt dumble shaped and are not toothed. They are not used for feeding but are useful for moulding wax into cells for comb (next) building.

Libium: The glossae are greatly elongated to form a hairy, flexible tongue. The glossa terminates into a small circular spoon shaped lobe called flabellum, which is useful to lick the nectar. Labial palms are elongate and four segmented.

Maxillolabial Structures: Maxillobial Structurev are modified to form the lapping tongue. The tongue unit consists of the two galeae of maxillae, two labial Palpi and elongated flexible hairy glossa of labium.

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. The tongue (glossae) is trusted into flower, which gets smeared with nectar. It is then retracted between labial palps & galeae. Nectar is then squeezed by galeae and is deposited in the cavity formed by the paraglossae. Accumulated nectar is then drawn into oesophagus by the pharyngeal pump.
