Morphology

labial + palpus

The term is compositional: 'palpus' names a mouth appendage and 'labial' specifies its location by the labium/lip area. This anatomical compounding directly predicts an appendage on the front of the mentum involved in sensing, so a learner who knows both constituents can infer the MWE's meaning.

Etymology

Labial palpus is a small jointed feeler next to an insect's mouth; labial means 'lip' and palpus means 'feeler'. These little 'feelers' help the insect taste and move food, so the name shows where they are and what they do.
