showing the major components of the chemosensory system. (B)
High-magnification scanning electron micrograph of a portion of the aesthetasc
tuft region of the lateral flagellum. Aesthetasc (a), guard (g), companion (c)
and asymmetric sensilla (as) are visible. (C) Scanning electron micrograph of
a portion of the medial flagellum showing various types of non-aesthetasc
sensilla. (DF) High-resolution scanning electron micrographs of three
bimodal chemo-mechanosensilla: (D) hooded sensillum, (E) medium simple
sensillum and (F) long simple sensillum. Modified from Cate and Derby
(2001).
