Polymorphic variations may act on chromatic alterations, which in excess cause hyperpigmentation (melanic individuals), and when deficient are responsible for hypopigmentation (albinism, leuctic or piebald individuals) and may be associated with ecol

Body color polymorphism of urban populations of cosmopolite fly Drosophila kikkawai Burla, 1954 was investigated in relation to its possible association with environmental temperature. Samples of D. kikkawai were collected in spring, summer, autumn a
