RESULTS COLEOPTERA Altogether 1862 specimens of 46 species were trapped. A majority of them are phytophagous, a smaller part is predacious, hunting on the vegetation or on the soil surface; the number of the coprophagous species is very low (for comparison see Ádám (1986)). Among the 70 species which were collected by isolators (see in Papp 1995 and Ádám in litt.) only 18 species were pan-trapped (i.e., a sum of 98 beetle species were recorded in this study). The abundance of the species is highly uneven; most of the species, which were recorded regularly, was mostly found in low frequencies. The cerambycid species Plagionotns floralis is one of the exceptions, since it was collected regularly and in adequately high numbers at Kunszentmiklós in the summer period. There is a limited number of species which were abundant while swarming, e.g., Mylabris pannonica, a meloid species. Much contrarily to the flies, the specimens of the coprophagous beetles were trapped in low numbers. Since these species orientated well by their smelling and they are good fliers at the same time, they are far less driven by the stochastic processes than small flies. They are able to find sheep droppings from a longer distance with a high probability. Only a part of the species which had formerly been found in sheep dung in Hungary was collected in the course of this study (cf. Ádám 1986). The detailed results on the beetles of these sheep-runs are published in a separate paper (mainly owing to the length of this paper). DIPTERA Altogether 18 949 dipterous specimens were pan-trapped. The sample series of FP921006 contains only 12 individuals: Sciaridae 1, Metopina sp. L, Adia cinerella 1, Lucilla sericata 1, Pollenia sp. 1., Sarcophaga moldavica 1, Ravinia striata 1, Bellieria melanura 2, Sarcophagidae indet. 1 (female), Tachinidae sp. 1. 1, sp. 2. 1. The flies identified in the other sample series are summarized in 29 tables (Tables 1-29), of 16 columns each and of the number of rows identical with the number of species in the given series (i.e., nearly 100 in some cases). No significant difference between the five "groups" of four traps each was detected, except for that case (Vértesboglár, 13th May 1992) where the total abundance distribution of Diptera was as follows: 063 053 048 045 » end 086 094 088 064 « 101 124 130 155 » 225 197 159 167 « start A direction of the wind The tendency is even more clear (and the assumption of the wind effect is better supported) if we neglect the calyptrates (i.e., the good fliers):
