Vinegar Fly
A tiny tan fly with bright red eyes that seems to appear out of nowhere the moment a banana starts to spoil, drawn in by the smell of fermentation rather than the fruit itself. Few insects have contributed more to the science of genetics, making this unassuming kitchen visitor one of the most studied animals on Earth.
