...was this lovely comma butterfly (Polygonia c-album). Unlike many other butterflies, it stayed put when I started to take pictures with my phone, so I had plenty of time to get a reasonably good shot. At first its ragged appearance made me think it was near the end of its brief life (three generations live and die each season) but now I realise the torn edges are a characteristic of the species. Perhaps it was so drunk on the verbena pollen that it did not notice me. It never stopped to fold its wings, so I didn't get to see the characteristic white punctuation mark which gives this attractive butterfly its name.
