Do insects have maxillae?

Maxillae (singular Maxilla) are part of an insect's mouthparts. ... Maxillae usually end in a sharp point and so the maxillae act like pincers. They are used to hold and manipulate food so that it can be chewed or sliced by the mandibles. The maxillae have palps - segmented appendages that perform a sensory role.

What animals have mandibles?

Mandibles are present in the extant subphyla Myriapoda (millipedes and others), Crustacea and Hexapoda (insects etc.). These groups make up the clade Mandibulata, which is currently believed to be the sister group to the rest of arthropods, the clade Arachnomorpha (Chelicerata and Trilobita).

Do insects have fangs or Maxillipeds?

A chewing insect has a pair of mandibles, one on each side of the head. The mandibles are caudal to the labrum and anterior to the maxillae. Typically the mandibles are the largest and most robust mouthparts of a chewing insect, and it uses them to masticate (cut, tear, crush, chew) food items.
