Observations

Members of CBC have limited experience with this species and to date it has only been encountered in mid-summer. Our first record was made by Giannis Gasteratos on the 1st August 2015. However, it was not until five years later, on the 4th August 2020, that Giannis, Anne Sordinas and Dan Danahar managed to find this species again. Then the next sighting came nine days later when the three returned with a group of ten CBC members, including: Jason Fisher, Tony Gould & Rob Kesseler, on the 13th August 2020. Whilst the butterflies were most commonly observed flying over rocky terrain and small mountain pastures, we did not find the host plant and subsequently could not observe the butterfly in association with it.
