An analysis was made of C-banding chromosomes of the following syrphid species (Diptera): Eristalinus aeneus (Scop.), Eristalis arbustorum (L.), Eristalis tenax (L.) and Myiatropa florea (L.).The results indicate that karyotypes of Eristalinus aeneus and Eristalis tenax have 2n=10 chromosomes, Eristalis arbustorum 2n= 12+10 microsomes and those of Myiatropa florea 2n=10 chromosomes.The examined karyotypes show only pericentromeric position of the constitutive heterochromatine. Eristalis arbustorum and Eristalis tenax have much larger C-positive blocks than Eristalis tenax and Myiatropa florea.In Eristalinu aeneus the secomd pair of autosomes is heteromorphic and the fourth onle is wholly euchromatic. In the sex chromosomes the C-positive segments has X while Y is always euchromatic.
