Fruit fly larva (maggot)

Moist environments rich in organic matter, such as overripe fruit, kitchen drains, garbage disposals, and compost bins.

Larvae feed on decaying organic material and the yeast or bacteria associated with fermentation.

Larvae are generally photophobic (avoid light) and remain submerged in their food source until they are ready to pupate, at which point they crawl to a drier surface.

Generally harmless to humans but considered a nuisance pest in homes and food facilities; they can potentially contaminate food with bacteria. In science, they are highly beneficial as a model organism for genetic research.
