Fruit fly

Natural Habitat

Typically found in homes, grocery stores, and areas with ripening or decaying fruit and vegetable matter.

Diet & Feeding

They feed primarily on the surface of fermenting or rotting fruits, vegetables, and other organic matter, specifically consuming the yeast and fungi associated with decay.

Behavior Patterns

They are active year-round indoors and are attracted to sugary substances. They have a very rapid life cycle, often developing from egg to adult in about 8 to 10 days.

Risks & Benefits

They are considered nuisance pests and can contaminate food by carrying bacteria like E. coli or Salmonella. However, they are highly beneficial to science, serving as a primary model organism for genetic research.
