53 species of the two families were found in the Świętokrzyski Region; they included 42 species of the family Calliphoridae and 11 species of the family Rhinophoridae, which account for 81% and 73%, respectively, of their numbers recorded from Poland. Most of them are widely distributed saprophages and parasitoids and predators of invertebrates and vertebrates. 6 species within these families are new to the region studied and Pollenia bulgarica is new to the fauna of Poland. 26 species are synanthropes. The highest number of 41 species was recorded in the mixed coniferous forest. The Calliphorid and Rhinophorid fauna of the Świętokrzyski Region was compared to that of blowflies and woodlouse-flies of other regions in Poland. An analysis of their species composition and dominance structure was earned out in seven habitats selected in the Pieniny Mts., the Bieszczady Mts., the Świętokrzyski Region, the Nida Valley and the Mazovian Lowland.
