Bracken Chafer

This little green and brown bug was gleaming in the sunshine this afternoon. I think it is a Bracken Chafer and can be a pest to grass or rose buds if in large numbers. I only saw one and we don't have any roses or grass (yet) so should be safe. 
The extra shows the babies which are getting big and showing lots of movement apart from opening their beaks. They are supposed to fledge at around 14 days which will be in a few days time.
