Its unlikely that this species is a resident on Corfu, yet. Most sightings of this butterfly start in late August or early September and in good years the highest abundance occurs in mid October. Indications are that this butterfly migrates in groups. If landfall takes place where the host plant adopted on Corfu occurs, courtship, followed by oviposition and the subsequent development of larvae, takes place.
John Denne and Anne Sordinas have both reared these larvae in captivity and have found that the adults emerge towards the very end of the year, in December. In years when the weather is mild, these butterflies may survive but in recent years Corfu has expereince some heavy dumps of snow and at this point the butterflies would not be expected to survive.
The spread of this species further north in the Mediterranean has been monitored by scientists over the last couple of decades and this change in species distribution is considered to be a climate change related phenomena.
