Yellow dung fly tongue. Coloured scanning electron micrograph (SEM) of the mouthparts of a yellow dung fly (Scatophaga stercoraria). At centre is the proboscis (pink) and at upper left and right are sensory palps (yellow). Flies do not have a muscular tongue like humans, but the tip of their proboscis has a similar sensory function. Research has shown that flies are able to taste a wide variety of flavours, and are especially adept at distinguishing between bitter flavours. Magnification: x180 when printed at 10 centimetres wide.
