House flies (Musca domestica), approximately 12 mm in length, flying about in laboratory cage. This species is the most common of all domestic flies and is such a pest and carrier of disease that it is the subject of countless studies and research. These flies have such a high reproduction rate that they are also kept as a convenient food source for other laboratory animals, like spiders, and other arachnids and arthropods.
