The labella are interconnected by a membrane called as Dutton’s membrane. It takes liquid part of the material as food. The flexible proboscis bends and the mandibles along with maxillae make a wound on the skin of the host.

The sucking action of muscles of cibarium and pharyngeal muscles help in sucking the blood through the food canal. (adsbygoogle = window.adsbygoogle || []).push({ The mouthparts are unfolded and spread apart. The mouthparts include labium, labrum-epipharynx, hypopharynx, mandibles and first maxillae. There are ridges on the inner wall of galeae which can reduce friction during drinking [9][10]. The maxillary palps are used for cleaning the antennae and also the front pair of legs. The serrated tips of maxillae keep the wound open. The tongue is extended and immersed into nectar. This biting and chewing type of mouthparts are considered as the most primitive and unspecialized of all the mouthpart types. Honey bee mouthparts are used for a number of important social interactions and nutritional functions: Feeding hypopharyngeal glandular secretion to developing larvae, grooming This feeding is analogous to inserting a straw into a drink to withdraw liquid. A pair of glossae is present between paraglossae. Lacinea is pincer like with two terminal denticles whereas galea is the outer soft hood life structure bearing long chitinous bristles. The glossa terminates into a small circular spoon shaped lobe called labellum, which is useful to lick the nectar. These mouthparts help the cockroach to bite and chew on hard stuffs, consume soft stuffs and also lap upon liquids.
