DISCUSSION There are 76 taxa of horse-flies that have been determined in the fauna of Croatia (Krcmar et al. 1996). Males are represented with 40 taxa, which is 52.63% of determined species. This result is probably conditioned by the differences in the behaviour of male and female horse-flies. Male horse-flies commonly fly very quickly over the paths in forests so that in most cases they stay out of reach for the sweeping net and other traps. This is also proved by the fact that most of the collected specimens were caught while they were alighting on a car. Females of most species need blood meals for the process of the development of eggs (Inaoka 1992). After mating, horse fly females usually suck blood on various vertebrates and therefore they are much more likly to be caught in various traps than the males, which is the reason why females are always represented in large percentage in every collected sample (Solem et al. 1990). This fact has been supported by our own results where there were only 202 male specimens (or 1.09%>) in the collected sample of 18,503 horse-flies. We have analyzed the behaviour of the males of 24 species collected in Croatia, the analysis was initiated by the fact that hovering and mating locations of European species of horse-flies have been insufficiently studied (Chvála et al. 1972). Other species of males were determined through the already published works on horse-flies of Croatia in which the authors - foreign entomologists gave no other data except for the name of the station, the number of collected specimens and the date when they were collected. The males of Tabanus autumnalis, Tabanus glaucopis, Tabanus sudeticus, Tabanus bromius, Heptatoma pellucens and Haematopota italica were collected in the woods consisting of oak and plain hornbeam of the association
