Fruit fly (Drosophila species)

Worldwide distribution, frequently found in kitchens, restaurants, and grocery stores where fermenting matter is present.

They feed on decaying organic matter, specifically the yeast and sugary liquids found in overripe or fermenting fruits and vegetables.

Fruit flies are known for their rapid reproduction and attraction to fermenting odors. They have a short life cycle (about 1 week from egg to adult) and are most active during daylight hours.

Risks: They are primarily a nuisance pest but can mechanically transfer bacteria and pathogens from sewage or trash onto fresh food. Benefits: They are invaluable in biological research as a model organism for genetics and development.
