A PURPLE FLOWER and it's wildlife - A BUTTERFLY enjoying his meal!

I was just relaxing in our garden when I saw some heavy wildlife going on at one of our plants. Luckily I had my iPhone6s close to me and managed to get a few shots. Here you can see the butterfly sitting at the flower:

Guess he just enjoyed his meal here - watch the proboscis of the butterfly going deep into the flower.

But he wasn't the only animal - there also were many bees on the flowers :)

Here is the plant without anything on it!

Can you tell me what plant and what butterfly this is? I will upvote the first right answer to each question via Hive account@randowhale :) Hope we will find the correct ones!
