Fruit fly

Natural Habitat

Found worldwide in association with human activities, specifically near ripening or rotting fruit and vegetables, garbage disposals, and fermented liquids.

Diet & Feeding

Larvae feed on yeasts and the breakdown products of fermentation from ripening fruit and organic matter; adults feed on the liquids of decaying organic material.

Behavior Patterns

Fruit flies have a very rapid life cycle, capable of maturing from egg to adult in about 8-10 days. They are most active during the day and are strongly attracted to the scent of fermentation.

Risks & Benefits

Generally considered a nuisance pest in homes and kitchens, they can potentially contaminate food with bacteria. Conversely, they are highly beneficial to science as an essential model organism for genetic research.
