Hoverfly fauna (diptera: syrphidae) of the eastern part of Serbia

One of the largest families of the order Diptera - hoverflies, are at the same time one of the most prominent insect groups, being recognized as the second most important pollinator group, bioindicator species, as well as potential biocontrol agents. Thus, raising interest in their distribution, biology and ecology is not surprising. As a contribution to the process of systematizing knowledge on these species, in this paper there are pre­sented details on the fauna of hoverflies of the eastern part of Serbia. It was done by incor­porating information on so far published findings, older, but unpublished records, as well as records collected in recent field trips across 109 localities in Eastern Serbia, all in one place. The most significant findings are Cheilosia subpictipennis Claussen, 1998 and Paragus kopdagensis Hayat & Claussen, 1997, published for the first time for Serbia, and 105 species registered for Eastern Serbia for the first time. Additionally, one potentially new hoverfly species for science is registered: Paragus aff. testaceus.
