A picture of a Fruit Fly Laying Egg
The small vinegar flies of the family Drosophilidae, commonly called fruit flies, have been exceptionally useful in scientific research. Their short reproductive cycle (a new generation of adults develops in only two weeks) and uncomplicated genetics make them ideal subjects for studies of heredity. This fly lays its eggs in rotting fruit and therefore does not need the stiff, sharp ovipositor that other fruit flies use to drill into fruits and stems. яндекс.ћетрика
