Fruit fly nymph / larva

Typically found on decaying organic matter, such as overripe fruit, or on moist surfaces in kitchens, drains, and compost bins.

Larvae feed on yeasts and bacteria found in fermenting organic materials.

The larva migrates and burrows into organic material to feed before climbing to a dry spot to pupate. They have a very rapid life cycle, often maturing in about 1-2 weeks.

Primarily considered a nuisance pest in households; however, they can potentially transfer bacteria and pathogens from decaying matter to fresh food. They are highly beneficial in scientific research as model organisms for genetics.
