Fruit Fly

Natural Habitat

Found globally in close proximity to humans, particularly near fermenting organic matter such as ripening fruit, compost bins, and drains.

Diet & Feeding

Primarily feeds on yeast found on decaying, fermenting organic matter and juices from overripe fruits.

Behavior Patterns

Attracted to the smell of acetic acid (vinegar) and fermentation. They have short lifecycles (about 8-10 days) and are most active during the day, performing intricate courtship rituals.

Risks & Benefits

Generally considered a nuisance pest in homes. They do not bite but can mechanically transfer bacteria or pathogens to food surfaces. They are highly beneficial to science as a primary model organism for genetic research.
