Size: Typically 2-4 mm (0.08-0.16 inches) long.

Fruit Fly

Natural Habitat

Commonly found indoors, especially around decaying fruit, vegetables, and fermenting liquids. Outdoors, they are found near ripe or rotting vegetation.

Diet & Feeding

They feed on fungi and yeast found on fermenting fruits, vegetables, and other organic matter. Larvae also feed on these decaying substances.

Behavior Patterns

Fruit flies are attracted to fermenting sugars. They have a short life cycle (about 7-10 days from egg to adult). Females lay eggs on the surface of fermenting food. They are typically seen flying in small swarms around their food source.

Risks & Benefits

Potential risks include being a nuisance pest indoors and potentially contaminating food with bacteria and other microorganisms if present in large numbers. They are not known to bite or transmit diseases directly to humans. Benefits include their use as a model organism in genetic and biological research.
