My friend in the next village phoned to tell me the huge buddleia was covered in fluttering painted lady butterflies so I jumped on the bus - had to run for it - and went along to look and wonder.
I also wonder what happened to them all in the torrential thundery rain which fell later in the day. Do they hide under the flowers? Do great heavy raindrops damage them?
I've been slowly answering the comments on this post.
