Sažetak

From 2018 to 2022, at 10 localities on Bansko Hill, 3,639 horseflies were sampled. Most specimens (3,404) were sampled in 2022 in the period from mid-May to mid-September. The horseflies sampled are classified into two subfamilies, six genera and 19 species. The species Hybomitra ukrainica (Olsufjev, 1952), Tabanus miki Brauer in Brauer and Bergenstamm, 1880, Haematopota grandis Meigen, 1820 and Haematopota pandazisi (Kröber, 1936) are new finds of horsefly species for the studied area. The species Tabanus tergestinus Egger, 1859 is the most abundant species and makes up 71.11% of the horseflies sampled. The species Tabanus bromius L., 1758 followed with 10.16% of the abundance, Tabanus sudeticus Zeller, 1842 with 8.82% and Atylotus loewianus (Villeneuve, 1920) with 5.74% of the horseflies sampled, while 15 other species of horseflies were represented by the remaining 4.17%. In the collected sample, male horseflies accounted for 51.71% of the sample; all of them were sampled with an oil liquid trap. The largest number of horseflies (84.14%) were sampled in localities on the northeastern side of Bansko Hill, covered with forest vegetation of secondary origin. Three species, T. bromius, T. tergestinus and Heptatoma pellucens, (Fabricius, 1776) have the longest flight period, from mid-May to mid-September. The highest peaks of abundance for T. tergestinus, T. bromius, and T. sudeticus were recorded in July, for H. pellucens in June and for A. loewianus in August. The greatest similarity in horsefly fauna (85.71%) was recorded in the localities Popovac and Karanac. 90.98% of horseflies were collected by liquid oil traps, followed by sticky traps (5.22%) and canopy traps (3.79%). Data from earlier studies from 2011 and data from the current studies in the area of Bansko Hill have yielded records of 22 species of horsefly.
