Note the two bilaterally situated scapes, which act as the first antennal segments. The right compound eye is evident at the top of the image, and appears to be constructed from shriveled grapes, which are actually ommatidia that were deformed in the specimen fixation process. The antenna is composed of three main regions: scape, pedicle, and flagellum. The scape attaches the sensory organ to the head region, and the pedicle joins the distal, jointed flagellum to the scape. The bilaterally situated antennae are not the only structures in the insect's repertoire of sensorial apparatuses that provide it with information of changes in its environment. In fact, the chitinous exoskeletal hairs, known as setae, as well as the grape-like ommatidia, which are the functional units of which the compound eyes are composed, all take part in providing the mosquito with environmental updates.
