Hyper realistic fly (Drosophila melanogaster) proboscis. This highly enlarged microcraph is based on Scanning-Electron-Microscopy, and was created and manually colored by Martin Oeggerli (Micronaut). His realistic paintings shed light on invisibly small matters. By dramatically enlarging and exposing his tiny and unfamiliar subjects, Martin Oeggerli creates a surrealistic tactility of subjects we can neither see, nor touch.
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.
