The mosquito mouthparts consist of the proboscis, paired mandibles and maxillae. Situated beneath the mandibles, paired maxillae manipulate food during mastication. The mandibles are caudal to the labrum and anterior to the maxillae. The mandibles are positioned between the labrum and maxillae. The mouthparts consist of pairs each of mandibles, maxillules (second pair of mouthparts) and maxillae. The mandibles are followed by paired first and second maxillae. They have a pair of elongated mandibles, and two pairs of maxillae. The hypopharynx is a somewhat globular structure, located medially to the mandibles and the maxillae. The mandibles and the maxillae are used for piercing the skin. The mouth parts contain a maxillae, a labium, and a set of mandibles. The lobster's head bears antennae, antennules, mandibles, the first and second maxillae. In addition, there is a pair of mandibles and two pairs of maxillae. The labium typically is a roughly quadrilateral structure, formed by paired, fused secondary maxillae. The maxillae and labium have palps that help termites sense food and handling. The labium is formed by first maxillae in diplopoda forming the gnathochilarium.
