My insect of the day, although not strictly an insect, turned up in a plastic bag delivered by a neighbour from her potato patch. Never seen one in my Puff.

A worm which was yellow at both ends and otherwise black. Its was all curled up and reminded me of a piece of discarded thin cotton thread and I expect had I taken the time to unravel it it would have been about 4 inches long but I did not want to harm it. It seemed quite happy and was gaily waving one yellow end about as if it were trying to attract attention. Any ideas what it could be? Too small for a photo I'm afraid.
