Drosophilidae facts for kids
D. melanogaster is not so much studied in the field as in the laboratory. The best-known studies of Drosophila in a natural environment was done by Dobzhansky and colleagues on Drosophila pseudoobscura from the early 1930s to 1970. Reprints and discussions are in Lewontin et al 2003, and theoretical discussions in Dobzhansky, 1970.
The cells of fruit flies usually do not divide after the imago is hatched. The fruit fly is mostly composed of post-mitotic cells, has a very short lifespan, and shows gradual ageing. As in other species, temperature influences the life history of the animal. They live longer in colder weather. Several genes can be manipulated to extend the lifespan of these insects.
There is another, unrelated, family of flies, the Tephritidae. It also includes species known as "small fruit flies".
