Fruit fly larva (maggot)

Natural Habitat

Found near fermenting organic matter, overripe fruit, vegetables, and drains.

Diet & Feeding

They feed on fungi, bacteria (such as acetic acid bacteria), and yeast found in rotting or fermenting vegetation.

Behavior Patterns

Larvae are highly mobile, burrowing through food sources to feed. They undergo three instars (growth stages) before crawling to a dry surface to pupate. They are most active in warm, humid environments.

Risks & Benefits

Generally considered a nuisance pest in homes and food facilities; they can potentially transport bacteria from unsanitary sites. In a scientific context, they are invaluable model organisms for genetic research and contribute to the decomposition of organic matter in the ecosystem.
