Buddleia and Butterflies

It is well known fact that if you plant buddleias in your garden and it will attract the butterflies.With all the sun we have being having of late the flowers are now at their best and the butterflies are loving them. There was 5 butterflies on one head but they don't stay long and I wasn't quick enough to catch them with the camera. They are starting to come into the house now as the nights draw in they are looking for a place to sleep for the winter.They like the top of the staircase and behind the wardrobe in our bedroom.They latch on to the beams too. For us it is a yearly event for others they view them with interest. All part of living in the country.
