Hairy Yellowish-Green Caterpillar

On the top of the bridge crossing the Keil Burn in Lundin Links noticed this strange looking caterpillar. Not sure of the identification. The only photo in my field guide that it looked remotely like was  a pale tussock moth caterpillar. However, the guide says that it's range does not extend to Scotland. I suppose that, perhaps, with the warm summers it's coming further north.


The hairs of the pale tussock moth caterpillar (Dasychira pudibunda) are an irritant and can cause a painful rash.
