Watch where you put your feet!

I was walking along the pavement today and spotted this colourful and fast moving caterpillar just in time. It looked quite determined to get somewhere so a quick shot was taken so as not to detain him for too long, much to the amusement of passers by who obviously wondered why I was kneeling down on the pavement.
The internet tells me it's Sycamore Moth Caterpillar which would make sense as the road is lined with Sycamore trees.
