Wings
I was aware of fluttering when I entered a very small ladies toilet ( that's small space not ladies!) Soon in front of me on the door was this wonderful specimen. Clearly, I had disturbed it's peace but once there was no movement, it took it's rightful place again.
Amazing what you can see spending a penny!
Relentless Optimism 
Almost looks too perfect to be real. What a surprise the butterfly and the door complement each other.
