Caterpillar identity please?

[Grandma]

Found this beautiful creature munching its way through the sweet basil on my kitchen window sill! I've Googled caterpillars without any success - I think it's a moth rather than a butterfly.

That looks like it, Manics!

It was such a beautiful looking thing, I just had to find what it was - and knew the clever folks on here would know!

Thanks, to you all, for your help.
