Barry took some more photographs. (Can you tell he has a new lens to play with?) Barry thinks the female spider has wrapped her defunct mate - the equivalent of putting food into the larder. I argued that it might not have been her mate and how did he know it was a female anyway? He riposted, 'You can tell by the size of her mouth!' He decided at that point to go elsewhere before any harm befell him.
If you're not tremendously squeamish you can see more detail by enlarging the photo. Look closely and you will see legs inside the cocoon.
