Antenna: noun, biology; An antenna (plural antennae) is a sensory organ, almost always one of two, that can be found on the head of an insect. Antennae are sensitive to touch, smell and, in some species, sound. Antennae are made up of several segments and different groups of insects have different forms of antennae (from the Amateur Entomologists’ Society website, which has excellent descriptions of the various types of antennae). The examples shown below are of plumose antennae, on the head of a Yellow belle moth. Having feather-like antennae like these increases the surface area available for the receptors a male moth uses to detect the pheromones of a female.
