Natural Habitat

Commonly found in homes, restaurants, and grocery stores, especially near ripening or rotting fruit and vegetables.

Diet & Feeding

Larvae and adults feed on fungi and the microorganisms found in decaying vegetable or plant matter, particularly fermenting fruit.

Behavior Patterns

Fruit flies are attracted to light and the smell of fermenting material. They have a very rapid life cycle, developing from egg to adult in about 8 to 10 days.

Risks & Benefits

They are considered a nuisance pest in homes and can contaminate food with bacteria. However, they are invaluable to scientific research, particularly in genetics and biology.
