We report on the apparently successful overwintering in Batman and Siirt Provinces, Turkey of Pontia glauconome , a pierid recorded in south-eastern Turkey for the first time in autumn 2016. Details of recent field observations of P. glauconome are provided and we discuss and illustrate early stages found on Reseda aucheri , a possible new host-plant. The route by which P. glauconome may have entered the country along the Tigris River from Syria is proposed. Larvae were found to have been attacked by a hymenopteran parasitoid species of the genus Hyposoter ; the 'mummified' larval skin and the adult parasitoid are illustrated.
