Scientific Name: Drosophila melanogaster
Order & Family: Order Diptera, Family Drosophilidae
Size: 3 to 4 mm (0.12 to 0.16 inches) long

Natural Habitat
Commonly found in homes, kitchens, restaurants, and grocery stores near overripe produce and moist organic matter.
Diet & Feeding
Adults and larvae feed on rotting fruits, vegetables, and decaying organic material, specifically targeting the yeast growing on these surfaces.
Behavior Patterns
They have a very rapid life cycle (8-10 days). Adults are attracted to the smell of fermentation and are most active during the day, particularly in the morning and evening.
Risks & Benefits
Generally considered a nuisance pest. They do not bite but can mechanically transfer bacteria from waste to food surfaces. In science, they are highly beneficial as a primary model organism for genetic and developmental research.
