Ábrahám Levente – Farkas Sándor: Butterflies along the river Drava, 2008
I The floodplain of Drava is not an evenly plain terrain, instead the landscape-transforming effects of the river are preserved In the form of smaller or greater elevations. Higher terrain patches are occupied by hardwood gallery forests with lush vegetation. In these forests the vegetation is dominated by pedunculate oak, common ash and elm species. Forest clearings, sunlit edges and glades are extremely important butterfly habitats. The most characteristic species in the butterfly community of the forests that are humid all year long are mostly the large-bodied brush-footed butterflies.
