Vapourer Moth Caterpillar

We found this amazing looking caterpillar (Orgyia antiqua) eating our basil. It's the vapourer moth caterpillar, but a bit disappointed to see the moth it develops into isn't anywhere near as interesting looking.

It seems it eats almost anything that it finds itself on and then pupates amongst twigs and leaves. Some people seem to find it a problem as they get such large colonies but we only found this one - shame (kind of) as it's the best looking caterpillar I've ever found!!
