Lime hawk moth - (Mimas tiliae)

[Russell England]

I don't know anything about moths, but after looking through several
pictures on the internet, it appears we had a lime hawk moth (Mimas tiliae)
in our garden yesterday afternoon.

It was at the bottom of our silver birch tree. I have a picture of it for
anyone that is interested.

Is this a rare moth?

Our approximate coordinates are:

Latitude 52.469 decimal degrees North
Longitude 2.159 decimal degrees West

which is Wollaston, Stourbridge, West Midlands, UK

Cheers
