Fruit fly (nymph/larva/indoor infestation context)

Natural Habitat

Commonly found in residential kitchens, restaurants, and grocery stores; outdoors in gardens and orchards with decaying fruit.

Diet & Feeding

Larvae eat sugary, fermenting, or decaying organic material such as overripe fruit and vegetables; adults feed on the yeast and liquids produced by fermentation.

Behavior Patterns

Rapid life cycle that can be completed in approximately 10 days; highly attracted to the smell of acetic acid (vinegar) and ethanol.

Risks & Benefits

Generally considered a nuisance pest but can contaminate food with bacteria (e.g., E. coli, Salmonella); invaluable as a model organism in biological and genetic research.
