It was the strong orange colouring and the beautiful scallopped wings that enabled me – a beginner in terms of butterfly names – to decide what this butterfly was. When I zoomed in on my photos, I was also able to see the white “comma” on the underside of the wings. (In German this is interpreted as a letter “C”, thus the German name “C-Falter”.)
Like all the butterflies to visit my garden, it loved the Centranthus ruber (Red valerian) and the lavender. This was about two weeks ago, when my lavender was still in full bloom.
