Maxillae(redirected from Maxillæ)
Also found in: Dictionary, Thesaurus, Medical.
in myriopods and insects, the second pair of jaws; in crustaceans, the second and third pairs.
In the chewing insects, the maxillae are used to tear apart and puncture the prey or grind the food; in the sucking insects (for example, butterflies), they form the tongue. In myriopods and insects, the maxillae are modified extremities of the fifth head segment, and in crustaceans, of the fifth and sixth head segments.
