Proboscis of blowfly. Coloured scanning electron micrograph (SEM) of the proboscis of a blowfly,Calliphora vomitoria,also known as the blue- bottle. The labella (two lobes,coloured grey) are seen,with parallel grooves (pseudotracheae) channelling into a central hollow tube. The proboscis is used for the ingestion of food,and acts like a sponge. Enzymes are exuded from the proboscis onto the food substrate (rotting animal or vegetable matter). These enzymes digest the food,turning it into a pulpy liquid,which is then sucked up by the proboscis. Further digestion takes place within the fly's gut.
