Description:
At a magnification of 1504x, approximately four times greater than PHIL 8789, this scanning electron micrograph (SEM) revealed some of the morphologic features of an Anopheles dirus mosquito's antennae. In this particular view, only the first two segments of the left antenna are visible, however, the antennae are composed of three basic segments: the proximal 1st segment known as the "pedicel" (seen here at Rt), the middle segment, or "scape" (Lt), and the third multi-segmented region known as the flagellum (not visible).Covered with sensorial "hairs", which aren't really hairs at all, but exoskeletal chitinous extensions, known as "setae", they provide feedback to the mosquito as to chemical, thermal, and tactile changes in its environment.
