We report on the presence of Issoria lathonia (Linnaeus, 1758) (Lepidoptera: Nymphalidae: Heliconiinae) in the Troodos Mountains in Cyprus. Although a very common species in parts of Europe, I. lathonia was not recorded in Cyprus until 2016, when a singleton was seen. No further observations of this rare species in Cyprus were reported until April 2023, when further singletons were observed by two of the authors of this paper. It is hoped that by creating awareness of the rarity of Issoria lathonia in Cyprus, further reports might be forthcoming. [ABSTRACT FROM AUTHOR]
