Detailed explanation-1: -Insects do this with the pair of antennae on their heads. But insects don’t only use their antennae to smell. They can also use them to feel the surface of an object, sense hot and cold, listen to sounds or detect the movement of air or wind. Insects have paired antennae so they can smell in stereo.

Detailed explanation-2: -Insects “smell” with their antennae. Pheromone-binding proteins (PBP) pick up pheromones at pores in the outside of the antenna and carry them through a watery layer to the nerve endings, where they are released.

Detailed explanation-3: -The antennae are often called ‘feelers’ because the insect waves them around. This is a wrong name because they are not only used for touch. The antennae are actually the insects ‘nose’-they are used for the sense of smell. The paired antennae are made up of a number of individual joints.

Detailed explanation-4: -Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially smell or taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate.

Detailed explanation-5: -How do cockroaches and butterflies feel the changes around them? Ans. Cockroaches and butterflies have antennae which help them feel changes around them. 4.
