Autumn is spider season, or at least the time of year when a lot of species become more visible, both around the home and outdoors. or many spider species, autumn is the mating season.
I don’t know if this little spider is one of those. It was busy rushing round its web, which was on the bridge carrying the Castlecroft road across the Railway Walk. As it moved, it cast a sharp-edged shadow in the bright sunlight.
