Fruit Fly pupa

Commonly found in residential kitchens, restaurants, and grocery stores where overripe fruit or decaying organic matter is present.

As larvae, they feed on yeasts and bacteria found in fermenting fruit and decaying organic matter; as pupae, they do not feed.

The pupal stage is a sedentary transformation phase where the larva hardens its skin into a puparium to undergo metamorphosis into an adult fly.

Generally harmless to humans but considered a significant nuisance pest in homes. They can potentially transport bacteria from decaying matter to food surfaces, posing a minor sanitation risk.
