Fruit Fly

Natural Habitat

Typically found in homes, grocery stores, and restaurants near ripening or decaying fruit and moist organic matter.

Diet & Feeding

Larvae and adults feed on yeast and bacteria associated with decaying fruit and fermenting organic materials.

Behavior Patterns

Drawn to the smell of fermentation; they have a very rapid life cycle (approx. 8-10 days), often leading to sudden infestations. Most active during the day.

Risks & Benefits

While they do not bite, they can contaminate food with bacteria and pathogens. In science, they are highly beneficial as a model organism for genetic and developmental research.
