Lackey Moth Caterpillar

Despite a solid day of gardening (me) and garage-organising (Mr PP), we weren't too tired to go for our usual walk. On the way home, though, we sat on a bench at the northern edge of the village, looking over the valley and across the fields to distant Dartmoor. So I was pretty proud of myself for spotting this caterpillar, perching on a twig on the hawthorn hedge (the caterpillar, not me). My Extra shows the caterpillar in broader context - can you spot it?

I think it's the caterpillar of the Lackey Moth (Malacosoma neustria). I've never seen one before.
