Ladybird in December

I thought I'd take a photo of the little flowers on one of my Hebes, then spotted this ladybird wandering over it. I also saw a wasp flying around the front door. Don't they know it's 5C in December?

When strolling through the garden,
If you should chance to see
A ladybug out walking,
Please say "hi" for me!
For ladybugs are good bugs,
They help the garden grow
They will bring you good luck,
So always say "hello!"
