The clypeus is one of the sclerites that make up the face of an arthropod.
A compound eye is a visual organ found in arthropods.
The labrum is a flap-like structure that lies immediately in front of the mouth in almost all extant Euarthropoda.
Insect mandibles are a pair of appendages near the insect's mouth, and the most anterior of the three pairs of oral appendages.
Palps serve as organs of touch and taste in feeding and in the inspection of potential prey.
