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.

Touch receptors stop responding during constant stimulation due to a process known as adaptation, which is a characteristic feature of many tactile sense organs.1

When a stimulus is applied constantly, these receptors undergo a temporary loss of sensitivity. This allows the nervous system to filter out persistent, unchanging information, enabling the organism to focus on new or changing stimuli in its environment. While the exact mechanisms can involve changes at the level of the receptor itself—such as the way mechanical pressure causes the deformation of structures like Pacinian corpuscles and the subsequent shift of chemical ions—the process is essential for maintaining an efficient sensory system.1

It is important to note that this adaptation is not necessarily a complete "shutting off" of all neural activity, as the nervous system as a whole continues to process and screen information to ensure survival and appropriate behavioral responses.23
