Marmalade hoverfly

I wanted to take some more macro images in the garden today but it's too breezy to try anything worthwhile.

Whilst sitting at our patio table, which happens to be covered with pots and plants, I noticed this little fellow darting around a Nasturtium.

It's a 'Marmalade hoverfly' or Episyrphus balteatus, quite common but until I checked I didn't realise there are so many different types.
