Fruit fly pupa

Typically found near fermenting organic matter, such as ripening fruits and vegetables, and in compost bins or trash cans.

In the larval stage, they consume yeast and bacteria found in rotting or fermenting organic material; pupae do not eat.

The pupa is a stationary life stage during which the insect transforms from a larva into an adult fly; this stage lasts about 4–5 days at room temperature.

Generally considered a nuisance pest in homes; they do not bite, but can potentially spread bacteria from contaminated surfaces to food.
