Fruit fly larva

Natural Habitat

Found globally in close proximity to human dwellings, specifically in rotting fruit, compost, or damp organic matter.

Diet & Feeding

Larvae feed on microorganisms (primarily yeast) that grow on decaying organic matter and fermenting fruit.

Behavior Patterns

Larvae undergo three instars (growth stages) before pupating; they are extremely fast-growing and tend to tunnel into their food source to feed constantly.

Risks & Benefits

While they do not bite or sting humans, they are considered a major pest in homes and food facilities as they can contaminate food with pathogenic bacteria; however, they are invaluable to science as a model organism for genetic research.
