Ábrahám Levente – Farkas Sándor: Butterflies along the river Drava, 2008

The host plant for the caterpillars of scarce swallowtail (Iphiclidespodalirius) [41] is blackthorn and hawthorn, or in cultivated lands the leaves of various stone-fruit trees. The phenomenon of hilltopping' is a typical behaviour of swallowtail butterflies: at mating time, specimens find each other by locating the highest points of the terrain. In such places, males often exhibit territorial behaviour. In the high summer season, meadow browns (Maniola)urtina) [42] are seen flying in all of the habitats along Drava.
