Insect antennae are sensory organs that allow insects to detect their environment. They are typically composed of two parts, the feelers and the palps. Feelers, also known as antennae, are long, thin appendages that protrude from the head of an insect and are used to detect movement, vibrations, and smells. Palps are short, finger-like appendages located near the mouth of an insect and are used to taste and manipulate food. Together, these two structures help insects to sense their environment and interact with it.
