The number o f species differs in various habitats o f the town. There are 13 species in the suburbs and 17 in urban green areas, including 16 in parks, 8 in green areas o f housing estates, and 7 species in the centre of the town.'parasites o f earthworms (17 species) are richer in species than parasites o f snails (2 species), toads and frogs (1 species). IN T R O D U C T IO N Flies o f the family Calliphoridae are poorly know n bo th in Poland and in the whole Palaearctic. So far they have n o t been studied extensively in M azovia and Warsaw. F rom W arsaw four species were recorded [7], and now 18 species are known. F rom the M azovian Lowland, five species were recorded, including three listed by S z n a b l [7], one quoted by S a n d n e r [5] and one by S c h u m a n n [6]. N o w 22 species of parasitic flies of the family Calliphoridae are known. O f the 17 species no t noted from the M azovian Lowland earlier, one is new to the fauna o f Poland. The objective of this paper is to analyse the species com position of Calliphoridae parasitica occurring in the M azovian Lowland and Warsaw, and also a zoogeographical and ecological analysis o f the collected material. The present contribution is mostly based on the m aterials collected in W arsaw in , and in the M azovian Lowland in , by m eans o f M oericke s traps suspended in tree crowns. Five- and nine-day samples were collected continuously over the growing season. Also included are m aterials collected for m ore than 20 years by m eans o f traditional m ethods such as sweeping, light traps, and catching by entomological net. In addition, unpublished m aterials from the collection o f S z n a b l, caught alm ost 100 years ago in M azovia and W arsaw, have been used. In the M azovian Lowland, flies were caught by M oericke s traps in the following localities: H am ernia (oak-hornbeam forest and carr), Radziejo wice (park), W ola M rokow ska, M łochów, and K am pinos forest (mixed coniferous forest, and pine forest).

The suburbs : U rsynów (park), allotm ents near Okęcie, Bielany (oak-hornbeam forest), Jelonki and Białołęka D w orska (oak-hornbeam forest, mixed coniferous forest, an d pine forest); u rb an park s: Łazienki, Saxon G arden, Praga, and Cem etery of Soviet Soldiers; green areas of housing estates: W ierzbno and Stawki; the centre o f the tow n: K onstytucji Square and the courtyards at K oszykow a street and at the Institute o f Zoology a t Wilcza street. The study area, m ethods and underlying premises are characterized in detail elsewhere [1, 2, 4, 8]. SPECIES CO M PO SITIO N In the M azovian Low land, 22 species o f Calliphoridae parasitica have been recorded, or 68.7% of these flies know n from Poland. In Poland, 52 species have been recorded so far, including 32 parasitic species (Table 3). In W arsaw, 18 species o f Calliphoridae parasitica have been recorded, which account for 81.8% of these flies know n from the M azovian Lowland. The M azovian Lowland an d all types o f green urban areas have five species in com m on. These are Bellardia biseta, B. pusilla, Pollenia rudis, P. varia, and Protocalliphora azurea chrysorrhoea. In the suburbs o f W arsaw 13 species have been recorded, and in urban green areas 17 species, including 16 in u rb an parks. The parasitic Calliphoridae occurring in green areas o f housing estates are p oo r, only eight species being recorded there, thus only one species m ore than in the centre o f the town. A t Konstytucji Square only single specimens o f three species. Pollenia rudis, P. varia, and Bellardia pusilla, were caught. Only two species of the genus Pollenia R.-D., recorded from M azovia and other regions of Poland in wet habitats, are absent in W arsaw. Z O O G E O G R A P H IC A L AN ALYSIS In b o th the M azovian Low land and W arsaw, the E uropean element is represented by the greatest n um ber o f species (Table 1). In the suburbs and in all types o f urb an green areas, the num ber o f species belonging to particular zoogeographical elements drops, while the p roportions am ong them are similar to those in M azovia. Only the Euro-Siberian element has been eliminated from green areas o f housing estates and from the centre o f W arsaw.

They account for 80% of all the species of this family. A dult parasitic Calliphoridae are melliphages. Their m ain food consists o f nectar and pollen o f m ore th an ten p lan t families, as well as o f honeydew produced by aphids and scale insects. Their larvae parasitize earthworm s, snails, frogs, toads, and birds. In M azovia and in all types o f urban green areas, m ost of the species represent Calliphoridae the larvae o f which parasitize earthw orm s, m uch less species parasitize other groups (Table 2). In the M azovian Low land, 13 species of earthw orm s have been recorded [3], of which two species, Allolobophora chlorotica and A. caliginosa are hosts o f flies of the genera Pollenia R.-D., and one species, Eisenia foetida, is parasitized by flies o f the genus Onesia R.-D. Lucilia bufonivora, a parasite o f Bufo bufo (L.), Rana temporaria L., and R. esculenta L., has been caught only in the M azovian Low land; it has n o t been recorded even from the suburbs o f W arsaw. Parasites o f snails are know n from M azovia and from urban green areas, except from the centre o f the town. M o st o f the parasitic Calliphoridae are m ore ab u n d a n t in M azovia, the suburbs, urban parks, and green areas o f housing estates, than in the centre of Warsaw. Bellardia pusilla is m o re ab u n d a n t in the suburbs, u rb an parks, and green areas o f housing estates o f W arsaw th an in the M azovian Lowland.

W Warszawie złowiono 18 gatunków (w tym jeden nowy dla fauny Polski Pollenia mayeri), co stanowi 81,8% fauny tych muchówek znanych z Mazowsza. W suburbium Warszawy występuje 13 gatunków pasożytniczych Calliphoridae, w zieleni miejskiej 17 gatunków, w tym w parkach m iejskich 16, w zieleni osiedlowej 8, a w cen trum 7 (na placu Konstytucji tylko 3 Bellardia pusilla, Pollenia rudis i P. varia). Zarówno na Nizinie Mazowieckiej jak i w Warszawie najwięcej gatunków należy do elementu europejskiego. Większość gatunków pasożytniczych Calliphoridae Mazowsza i Warszawy związanych jest z terenami zadrzewionymi. N a M azowszu oraz we wszystkich typach zieleni miejskiej pod względem gatunków przeważają Calliphoridae, które w stadium larwalnym są pasożytami dżdżownic; pasożyty ślimaków nie występują jedynie w centrum Warszawy, natomiast pasożyty ropuch i żab stwierdzono tylko na Nizinie Mazowieckiej. Większość gatunków pasożytniczych Calliphoridae liczniejsza jest na M azowszu niż na terenach zurbanizowanych natomiast Bellardia pussilla liczniejszy jest na przedmieściach Warszawy i w zieleni miejskiej niż na Mazowszu. Pollenia rudis jest najliczniejszym gatunkiem zarówno na M azowszu jak i w środowiskach zurbanizowanych.
