A large butterfly with orangey-brown upperside with a large black tip to the forewing with white markings. The body is unusual in that it is black with white spots. The unique character which enables positive identification from any other similar European species is a single row of white spots on a black margin on the hindwing, upperside and underside. In Corfu the butterfly should not be confused with any other species.
A highly migratory species, most frequently encountered along the coast.
Tropical Milkweed Asclepias curassavica and Swan Milkweed Asclepias fruticosa. In Corfu, John Denne, Lynne Williams, Bob Giles, Jan Wilkins and Anne Sordinas have observed oviposition and larval development on Cynanchum acutum subsp acutum.
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.
