Fruit fly (or Vinegar fly)

Commonly found in residential kitchens, grocery stores, and food processing facilities near fermenting organic matter.

Primarily feed on juices from overripe fruits and vegetables, and the yeast associated with fermenting organic materials.

Attracted to light and fermented odors; they have a very rapid life cycle from egg to adult in about 8-10 days under warm conditions.

Generally considered a nuisance pest. While they do not bite, they can potentially transport bacteria from unsanitary surfaces onto food products. In science, they are highly beneficial as a model organism for genetic research.
