Maxilla (arthropod)

Maxilla (arthropod)

In certain arthropods, the maxillae are paired mouthparts located behind the mandibles. While the mandibles are used for biting or cutting food, the maxillae are used for swallowing. Maxillae are found in all arthropods except for Chelicerata and the extinct trilobites, i. e. in myriapods, crustaceans and insects. The maxillae often bear palps (sensory feelers). Crustaceans and centipedes typically have two pairs of maxillae; in millipedes and insects the second pair is often fused together to form a labium (lower lip). In insects, maxillae may also be modified into a sucking proboscis.
