What is made of the scape, pedicel and flagellum?
Antennae are the primary olfactory sensors of insects and are accordingly well-equipped with a wide variety of sensilla. Paired, mobile, and segmented, they are located between the eyes on the forehead. The three basic segments of the typical insect antenna are the scape or scapus (base), the pedicel or pedicellus (stem), and finally the flagellum, which often comprises many units known as flagellomeres.
