The sense of smell is closely allied with the sense of taste. The organs of the sense of smell are simple nerve-endings in papillae or pits. The substance to be smelled must come to the organs of smell as a gas or vapor. This example shows the smelling pits on the expanded terminal segments on the antenna of a leaf-eating beetle.

Sound making amoung animals serves to aid in frightening away enemies or in warnng companions of their approach, for recognition among mates and members of a band or species. It also aids in the attracting and wooing of mates, and the interchange of information. The annoying, high-pitched, whining sound mosquitoes make is caused by their wings rapidly beating hundred of times per second. This diagram shows the auditory hairs on the antennae of a mosquito.
