There were dry stalks of weed on the pasture in front of the pan-traps, some of them higher than 50 cm (at a distance of ca 20 m). Those dry stalks were used by the small flies as "take-off points" easily lifted from the ground by the wind. This observation has much affected our idea about the dispersion strategy of small Diptera (see in the Discussion). Among the 112 species which were collected by isolators (for list see in Papp 1995) 63 species were pan-trapped (much contrarily to the ratio found for beetles). In the tables below numerous other dipterous species are listed and there is an addition of the species which were singled in the course of additional collections on the sheep-runs but not captured by isolators or pan-traps (i.e., a sum of dipterous species cannot be given exactly). An estimation of ca 330 species is made for Kiskunlacháza only. It is a matter of course that among the numerous species trapped, a good number of rare species was also found. Below only some examples are given for them as the most important faunistical results. Empidideicus hungaricus Thalhammer, 1911: one specimen of this minute bombyliid species was captured at Zámoly, Forráspuszta. This species was described from Vaskút (South Hungary) but the types were destroyed in the collection of the HNHM. Possibly this newly collected specimen may serve in the process of a neotype designation. Catharosia flavicornis (Zetterstedt, 1859): four males (first males from Hungary), Zámoly, Forráspuszta; they are brachypterous and as far as we are informed this is the first known tachinid species with brachypterous wings. Homalometopus platycephalus (Becker, 1907): one male of this ephydrid species representing a genus new to the Hungarian fauna was trapped (Kunszentmiklós, 19 May 1992, known from Tunisia and Italy, cf. Mathis 1984, Munari 1988: Fig. 2). Formerly found on sea-shores only. Our specimen is a freshly emerged one, i.e., this species breeds also in the saline marsh of Kunszentmiklós. INSECTS OTHER THAN BEETLES AND FLIES We would like to summarize only the number of specimens and of the species of other insect orders we found in the pan-traps (detailed results will be published elsewhere). Orthoptera: 43 specimens of seven species (det. T. Kisbenedek) Psocoptera: 1 Lachesilla pedicularia (det. Gy. Sziráki). Aphidoidea: 231 individuals, several species Homoptera: 431 individuals, 26 species(!) (det. A. Orosz). Heteroptera: 86 indiv. ofca 10 species Lepidoptera: 38 specimens (mainly Coenonympha pamphilus, a limited number of Lycaena and nymphalids) Hymenoptera: 1380 specimens (800 specimens of numerous (possibly up to 100) species of Ichneumonoidea, we have no hope to have them identified; almost all of the rest are ants: Lasius alienus, Formica pratensis, Myrmica laevinodis, etc.); i.e., 2210 insects other than beetles and flies.
