Skin piercing machinery - light microscopy. The tip of the Glossina pallidipes proboscis showing the arrays of rasps and teeth used to penetrate through the skin to find blood. Light microscopy images of the tip of the proboscis, inverted (a) and everted (b). The dark pigmented region is on the ventral side of the labella and there is a long array of teeth on the dorsal side. These dorsal teeth are on the left in the lateral view shown in a; the rasps near the tip of the proboscis are clearly visible through the labellum wall, with gustatory sensilla and denticles protruding slightly from the tip. In b the everted labella are seen in ventral view, with dorsal teeth visible on both sides. Both sets of rasps, each subdivided into three, are visible, and now the gustatory sensilla (gus) and prostomal teeth are exposed in a ring at the base of the rasps
