U razdoblju od svibnja do rujna 2011. godine obavljena su istraživanja faunisticko-ekoloških znacajki obada (Tabanidae) na deset lokaliteta uz rijeku Muru.Sakupljeno je 989 jedinki koje su svrstane u 2 podporodice, 5 rodova, 14 vrsta i jednu podvrstu.Najbrojnije vrste su Haematopota pluvialis, Chrysops relictus i Tabanus bromius. Najveci broj obada uzorkovan je u Goricanu 2, a najmanje u Donjoj Dubravi. Prema Sørensenovu indeksu faunisticke slicnosti najvecu slicnost imaju Sv. Martin na Muri i Mursko Središce, dok je najmanja slicnostizmeu Goricana 2 i Donje Dubrave.The faunistical and ecological research of horse flies was conducted from May to September 2011 on ten localities along the Mura River. During the research 989 specimens of horseflies were collected and classified in 2 subfamilies, 5 genera, 14 species and 1 subspecies. The most abundant species were Haematopota pluvialis, Chrysops relictus and Tabanus bromius. The largest number of horse flies was collected on Gorican 2 locality, while the smallest number of specimens was collected on Donja Dubrava locality. According to value of Sørensens index the most faunistical similarity was found between Sv. Martin na Muri and Mursko Središce localities,while Gorican 2 and Donja Dubrava were the least similar localities
