I photographed this butterfly a few days ago. To the naked eye it looked like a southern small white but when I looked at the photograph I noticed some features that are not mentioned in my butterfly guide. The outer margin of the forewing, around the dark mark, is striated and the margin is scalloped. Have I misidentified the species or is this simply an undocumented feature? Here's a close-up of the r wing showing the scalloped edge.
Did you take the photo in Morocco or in Southern Europe? That's the known distribution of the Southern Small White. But to me it looks more like a female Orange TipAnthocharis cardamines. Here are some photos on this page.
Great response, thank you. The photo was taken in central Spain (sorry I should have mentioned that). I just checked - I took 3 photos in total but no underwing surfaces were visible (which would have helped me not make that mistake). I also photographed a male orange tip the same day and not far away. Let's hope they found each other.
