Comparison of Macroheterocera assemblages of four forests in the Bereg Plain (Hungary, Ukraine)

Abstract

AbstractWe compared the macro-moth assemblages of four forests from which one is extended on the Ukrainian and three on the Hungarian side of the Bereg lowland, and additionally one in the adjacent part of the Hungarian plain (NE of Carpathian Basin). The data were collected by light trapping during at least in five years in all sites. Numerous faunistically significant and/or rare species were recorded. The species composition, faunal types and ecological components were rather similar in all sites, dominated by widely distributed Euro-Siberian species but with considerable participation of Boreo-Continental and Holo-Mediterranean – West Asiatic species. Considering the ecological connections of the species, the largest part of the assemblage is composed by species of different types of deciduous forests (oak woods and hardwood gallery forests) but also with significant proportion of wetland components (marshy-boggy habitats and tall forb communities) and generalist species. The similarity of the species composition proved to be high in all dominant taxonomical groups (Geometridae, Erebidae and Noctuidae, including the most diverse subfamilies). Several species have high conservation significance.
