Hummingbird hawk moth seen

I've enjoyed the sunny warm weather of late but we are promised a cold blast from the north next week, with the possibility of snow showers on higher ground at least. I had previously mentioned seeing butterflies on the wing; I've noticed brimstones, peacock and red admirals in the last week or so. But yesterday I was particularly excited to see in a friend's garden my first hummingbird hawk moth of the year! Wow, this really was a totally unexpected pleasure!
