Notes on species of the genus Agria R.-D. (Diptera, Sarcophagidae)

A key is given for the identification of females of all Holarctic species included into this genus, and keys are provided for distinguishing third instar larvae and puparia of two Palaeartic species. In addition to these, the description of the A. monachae (Kr.) female has been expanded

Parasitic Calliphoridae (Diptera) of natural habitats in the Mazovian Lowland and in Warsaw

The investigations were carried out in three zones: rural (I), suburban (II) and urban (III). 22 species (68,7% of the Calliphorid fauna of Poland) were recorded from Mazovia (I). In Warsaw there were found 18 species (81.8% of the fauna of these Dipterans from Mazovia). The material studied was dominated by widely distributed species the larvae of which parasitize invertebrates. An analysis was carried out of the species composition and the domination structure of the communities of parasitic Calliphoridae in the selected habitats of these zones (I-III)
