Showing 2 types of FRUIT FLIES
There are 91 species in what is called the Drosophila repleta “group” in North and South America and they are native to this Hemisphere. Given the sudden and recent appearance of these flies in North America they may be native to Central and South America.
Many species of these flies occur throughout the world. The species Drosophila melanogaster is one of the most common in structures, and is used extensively in laboratory studies of genetic characteristics.
