I'm fascinated by them. Apparently a scientist did an experiment once. He arranged the caterpillars in a head to tail circle with a food supply on the outskirts for when they got the munchies. They carried on doing trotting around for an entire week.

We didn't know this when we arrived. During our first lunch outside one fell on Salty Dog's lap. 'Oh how sweet!' she exclaimed 'Look at his lovely little face.' She then proceeded to stroke him as if it were a fluffy kitten. No ill effects yet. I think she might have had a lucky escape!
