An illustration of the common fruit fly (Drosophila melanogaster) as well as several fruit fly eggs in the background. While fruit flies are common household pests, they are also used by researchers to study genetics, physiology, pathology, and evolution. Each egg has two extensions known as respiratory filaments that are designed for gas exchange and repelling water, and typically hatch within 24 hours. | |
