Fruit Fly (Vinegar Fly)
Scientific Name: Drosophila melanogaster
Order & Family: Order: Diptera; Family: Drosophilidae
Size: 2.5 mm to 4 mm (about 1/8 inch) in length

Natural Habitat
Commonly found near ripening or decaying fruit, vegetables, and fermenting organic matter in kitchens, gardens, and food processing facilities.
Diet & Feeding
Larvae and adults feed on sugary and fermenting organic substances, particularly decaying fruit, fungi, and the yeast growing on these surfaces.
Behavior Patterns
Attracted to the smell of fermentation; they have extremely rapid life cycles, often developing from egg to adult in 8–10 days under warm conditions. They are most active during the day.
Risks & Benefits
Generally considered a nuisance pest in homes. While they do not bite, they can cross-contaminate food with bacteria and pathogens. Beneficially, they are one of the most important model organisms in genetic and biological research.
