Fruit Fly

Natural Habitat

Found worldwide in association with human habitats, particularly near kitchens, garbage, and ripening fruit.

Diet & Feeding

Larvae and adults feed on decaying organic matter, yeast, and fermenting liquids (sugar-rich substances).

Behavior Patterns

Attracted to the smell of fermentation; they have a very rapid life cycle, often going from egg to adult in about 8-10 days in warm conditions.

Risks & Benefits

Primarily a nuisance pest in homes; they can potentially transfer bacteria from dirty surfaces to food, though they do not bite humans. They are highly beneficial in scientific research as genetic model organisms.
