Lime Hawk Moth

The hubs was on the way out one day and called me out to see a "big butterfly" in the hallway.

I knew it was a moth, but never having seen anything like it before, I didn't know exactly what kind of moth.

I wiki-ed - apparently it's very common in London and the south. Clearly a Northern Lass like me didn't know that! It's a Lime Hawk Moth, and very pretty it was too!
