The fruit fly, scientifically known as Drosophila melanogaster, is a small insect commonly found in homes and gardens. These flies are attracted to ripe and decaying fruits, where they lay their eggs. Adult fruit flies are typically about 1/8 inch long and have red eyes and a tan body. Fruit flies are important in scientific research due to their short life cycle and genetic similarities to humans. They are often used in studies related to genetics, development, and behavior, making them a valuable model organism in the field of biology.
