Fly proboscis

Coloured scanning electron micrograph (SEM) of the tip of the proboscis (snout) of a fruitfly (order Diptera). Fruitflies possess mouthparts adapted for sucking and feed on plant juices. The tip of the proboscis in some flies has spongy structures which conveys liquid food to the mouth. Solid foods are dissolved in a drop of saliva & sucked up in the same way.
