Just as I was leaving Old Warden Tunnel NR a spider on the gate-post caught my eye, looking rather odd. I thought it might be holding prey but when when I looked closely realised it was starting to shed its skin. (Ecdysis is the fancy term). It had obviously fixed its rear end to the post with silk so as to allow all eight legs to be extracted from the old skin. Looks rather like it is trying to put on four pairs of really tight jeans. Finally it hung with all legs outwards, hardening. A fly chose the right time to land nearby! Seven minutes covers the sequence.
