Incursions of Belenois aurota (Fabricius, 1793), a vigorous, tropical migrant pierid, have become more common in recent years in countries of the southern Levant, with rare appearances in south-eastern Türkiye. Here, we report on the species presence in other Levant countries of the eastern Mediterranean, including Mediterranean Syria and, for the first time, in Cyprus, on which island B. aurota was discovered in 2023. We also report on experiences in south-eastern Türkiye, where, during the same autumn period, extensive breeding resulted in at least three local broods leading to significant population irruptions and dispersal. Likely migration routes via the Jordan Rift Valley System into countries of the Levant are discussed, and we introduce an additional migratory route east of the Lebanon, Anti-Lebanon and Silsilat al-Jib āl as-Sāhilīyah (Latakia) mountain ranges, not previously recognized to our knowledge. The value of the Tigris River as a conduit for migrant butterflies from the Middle East into the provinces of south-eastern Türkiye had previously been documented and is again well illustrated by numerous observations in south-eastern Türkiye along the river's route south from its origins in the mountains of eastern Türkiye. Although B. aurota is recognized as an obligate migrant, it is considered that 2023 weather systems assisted the arrival of the species into the northern Levant and south-eastern Türkiye.
