The relative frequency values of the individual families and the guilds - separately the summer and the autumn samples, the summary of the 18 biotopes - are given in Table 3. Table 3.

The ratio of the two web builder guilds as compared to each other is very similar in the two aspects. (In the case of other floral spider community, there can be important differences in the spring and autumn frequency of the two web builders (Szinetár 1992d). Parallel with the frequency increase of either of the web builders (from summer to autumn) the number of crab spiders, as well as of jumping spiders decrease alike. The relative frequency of hunters and pirates - similarly to the web builders, shows and increase compared to the early summer values. (Fig. 1) The changes in the relative frequencies of the individual families and guilds were examined along two transects (one closely following the N-S, the other the SW-NE axes of the town). Following the suburb - inner town II - inner town I - inner town II - suburb axis, I found assessable tendencies in two cases (Theridiidae, Salticidae). I show these families in Figs 2 and 3, where, against the proportionated map of the town, the biotopes, nearly along one transect (9, and 10, respectively), and the frequency values of the given taxon can be seen (Figs 2-3). Similarly to the species diversity and evenness calculations I calculated the guild diversity
