Fruit fly

Widely distributed worldwide; commonly found in kitchens, gardens, compost heaps, and near rotting organic matter.

They feed on fungi, rotting fruit, and other decaying organic materials, specifically the yeast produced during fermentation.

Fruit flies have a rapid life cycle, often completing it in about 7-10 days. They are most active during the day and are highly attracted to the smell of fermentation and vinegar.

They are primarily considered a nuisance pest in homes. While they do not bite or sting, they can mechanically transfer bacteria from contaminated surfaces to food. In science, they are highly beneficial as a model organism for genetic and developmental research.
