A small spider 8mm head to tail, whitish head. Waisted body.
No interactions present.
It might not be identifiable from a photo, but to help, please could you provide an idea of length (not including legs)?
Ta for the update - at the moment broadband problems mean I can't download the large-scale image to see if there's more detail, but I'll have a look when it's fixed.
