I was out without my camera on Sunday. This was a mistake as it was one of the best wildlife experiences I've had in recent times. Notable sightings included a whinchat, lapwings, swallows, (not quite a cuckoo, as I only heard it,) a heron in flight, a mountain hare and...an osprey!
But before most of that, I spotted these butterflies. I'm little better at butterfly ID than flowers, but I know a dandelion when I see it (dent de lion = lion's tooth) and I believe they were green-veined whites (although the veins look grey to me). And it doesn't really matter that I didn't have a proper camera with me - my phone did the work on this occasion, including this video in which not even a strong, gusty breeze or my proximity seemed to deter these hardy little insects:
