ABSTRACT

Overwintering success of Papilio demoleus Linnaeus, 1758, a recently arrived Swallowtail to
the Mediterranean basin, has been such that we are able to report on dispersal of the species into
50×5km2 -UTM squares in Cyprus. Citizen science reports, appropriately verifified, have been
invaluable in assessing the spread of a papilionid that was fifirst reported from Cyprus in August
2021. These observations, supplemented by others from members of the Cyprus Butterflfly Study
Group, point to a known area of occupation representing ca. 11% of the island in just one year.
However, the distances separating observations from the main concentration in central/eastern
areas of the island with those reported from coasts around the island, strongly support a belief that
the species has a far greater distribution in Cyprus. In turn, as the species has survived throughout
an unusually cold winter during 2021/2022, this leads us to hypothesize that a successful,
potentially permanent, range expansion has been achieved. Until more is known about the
adaptation of P. demoleus to pertaining environmental conditions in Cyprus, where fifive annual
generations appear achievable, we urge caution before the tag of ‘pest species’, as applied in other
parts of the world, is attached to P. demoleus in Mediterranean regions.

INTRODUCTION

Readers of the erstwhile sister journal Entomologist’s Gazette have perhaps become familiar with reports of the arrival in 2021 of Papilio demoleus Linnaeus, 1758 (Lime or Chequered Swallowtail) (Figs 1 & 2) in areas of the eastern Mediterranean. In Başbay, Salimeh & John (2020a & b) we commented on the recent discovery of the species at Mediterranean coastal regions of Turkey and Syria, and in John et al. (2021b), confirmed the presence (in Syria) to be that of nominotypical P. demoleus demoleus. The last-mentioned paper also confirmed the species’ dispersal into Lebanon and predicted further territory expansion by this vigorous swallowtail into Israel and Cyprus. Hecht (2021) reported arrival in northern Israel in the autumn of 2021, prior to which the anticipated arrival in Cyprus had been realised, with the discovery of P. demoleus on 11 August 2021 (John et al. 2021a). The species was first seen on the outskirts of Lysi (WD68SW), ca. 28km south-east of Nicosia, in a garden owned by the parents of the second author. Molecular analysis showed this to be P. demoleus demoleus (GenBank accession number OL742425), identical to the haplotype of the specimen from Syria (GenBank accession number MW390816), thus indicating a
