We recently took down our front porch because it was in danger of falling down. The wood was well past its best and I was worried that the door would slam and all the glass would fall out.
In the process of dismantling we found the following eight legged creature. It was about the size of a 50p piece and quite solid looking, you can see how big it is when you compare it with the snail shell . It had an interesting pattern on its back. In the right light it looks a bit like a skull.
