Results and discussion Melitaea arduinna Introduction Until 2007, there were no records of from Serbia. The closest records were from Vrška Čuka Nymphalis vaualbum (Denis & Schiffermüller, 1775) in Bulgaria (Abadjiev 2001) and northern Macedonia (Fig. 1) is a butterfly species with a Holarctic dis tri bu (Schei der & Jakšić 1989).
