From: Nano-architecture of gustatory chemosensory bristles and trachea in Drosophila wings
Electron microscopy photographs of the Drosophila wing bristles of the anterior margin.
(A) The wing anterior margin has two types of bristles. The stout and short ones are linked to the mechanosensilla, while the long hairs are associated with the gustatory sensilla. (B) Sensorial bristle made of chitin with a nano-pore at the top. (C) An opening made with a razor shows that the thin hairs are hollow tubes. These interior spaces shelter the lymph and the dendrites of sensilla neurons. (D) Collapsed nano-pore located at the apex of the bristle (scale bar = 300 nm).
