Under a magnification of 1213X, this scanning electron micrograph (SEM) revealed some of the morphologic features located upon the surface of one of the two antennae used by an unidentified 1/4"-sized black flying insect with a small red mark on its dorsum, in order to detect changes in the organism's environment such a wind speed and direction, chemical queues, i.e., pheromones, and variations in temperature. The antenna is composed of three main regions: scape, pedicle, and flagellum. The scape attaches the sensory organ to the head region, while the pedicle joins the distal, jointed flagellum to the scape.
