Wikipedia: Drosophila
Drosophila (/drəˈsɒfᵻlə, drɒ-, droʊ-/) is a genus of small flies, belonging to the family Drosophilidae, whose members are often called “fruit flies” or (less frequently) pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit.

Etymology
The term >“Drosophila”, meaning “dew-loving”, is a modern scientific Latin adaptation from Greek words δρόσος, drósos, “dew”, and φίλος, phílos, “loving” with the Latin feminine suffix -a.
