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.

In the study of senses, receptors are biological transducers that convert environmental energy into electrical impulses. They are categorized based on how they respond to stimuli:1

Steady-state receptors: These receptors generate nerve impulses as long as a specific condition, such as temperature, remains constant.1
Changing-state receptors: These receptors respond specifically to variations in the intensity or position of a stimulus.1

Essentially, while steady-state receptors monitor the persistence of a state, changing-state receptors are tuned to detect fluctuations or shifts in the environment. Both types are essential for the nervous system to report the intensity and location of stimulation effectively.1
