Voucher specimens of every species were preserved in alcohol until they were prepared (minuten-pinned, labelled, etc.) in the Diptera Collection of the Department of Zoology, Hungarian Natural History Museum (HNHM), Budapest. They are approximately 2,800 museum specimens (of the 92,680 individuals sampled). Of course, it occurred that I was not able to identify some specimens originally in alcohol. All these specimens were put aside in vials with alcohol, they were identified later with the aid of specimens of comparison in the HNHM (later prepared on pins, etc.). The time requirement of the identification of 92,680 individuals is estimated as ca. 300 to 350 working hours. Handling of the voucher specimens (drying, pinning, labelling, and repeated identification, placing them to the collection) is an addition, of course. RESULTS Qualitative results The original data have been set up on the link of http://www.nhmus.hu /-lpapp/ 1 . The first matrices were created in 2003 for the data from 2002 and 2003, where the list of species is given in a taxonomical order. Keeping that sequence, the list was complemented with the species, which were found in 2004 for the first time, and again, in 2005 the "newcomers" of that year were appended. This way it is easy to find the species, which appeared in 2004 and in 2005. The fly assemblage, which we found, is completely in accordance of former observations, and it is in coherence with the description of species succession described above. The most characteristic feature of the sample series is the 66.5% super-dominance of Coproica lugubris. Indeed, we think it a characteristic finding, an objective fact. However, at the same time it meant that the total number of individuals in our sampling series had to overrun significantly the planned 50,000 individuals. That number was proposed as a minimal aim in our plans (to achieve a suitable sample for analysing the species abundance distribution of the "rest", or almost so). That was why our two-year sampling was modified to three years. A sepsid species, Sepsis thoracica, was represented in high numbers, likewise Musca osiris WIEDEMANN, 1830 and Adia cinerella.
