Compound eye — Senses Vespid wasps (Vespidae), similar to other insects, have compound eyes that consist of thousands of tiny optical units known as ommatidia, which contain light-sensitive photoreceptor cells.

The vestibular system is the sensory apparatus within the inner ear responsible for maintaining postural equilibrium and coordinating head and eye movements. It functions through two primary types of sensory organs that detect acceleration:1

Semicircular Canals: These three loop-shaped structures are oriented in different planes to detect rotational (angular) acceleration. Each canal contains a fluid called endolymph and a sensory structure called the ampulla. When the head rotates, the movement of the endolymph deflects the cupula, bending hair cells and triggering nerve impulses.123
Utricle and Saccule: Located within the vestibule, these organs respond to linear acceleration and changes in head position relative to gravity. They utilize otoliths—tiny granules that shift when the head tilts—to deflect hair cells and signal movement to the brain.143

These organs transmit information via the vestibulocochlear nerve to the brainstem and cerebellum, which reflexively adjust the muscles of the eyes, neck, and limbs to maintain balance and visual stability.152
