Fruit Fly

Scientific Name: Drosophila melanogaster (common fruit fly) or other related species within Drosophilidae.

Order & Family: Order: Diptera, Family: Drosophilidae

Size: Typically 1.5 to 4 mm in length.

Fruit Fly

Natural Habitat

Fruit flies are commonly found in kitchens, grocery stores, restaurants, and other areas where ripe or fermenting fruits and vegetables are present. They are attracted to yeast and sugar.

Diet & Feeding

Adult fruit flies feed on ripe and rotting fruits, vegetables, and other organic matter. Their larvae (maggots) feed directly on the fermenting material where they hatch.

Behavior Patterns

Flies are typically active during the day, especially in warmer temperatures. They are known for their rapid flight and ability to quickly change direction. They lay eggs in decaying organic matter or food sources, which hatch into maggots (larvae). These maggots feed and grow, then pupate, and finally emerge as adult flies.

Risks & Benefits

Risks: Can be a nuisance pest, contaminating food and contributing to food spoilage. They can carry bacteria and other microorganisms from decomposing matter to food surfaces. Benefits: In scientific research, especially in genetics and development (due to their short life cycle and ease of breeding), Drosophila melanogaster is a vital model organism.
