I was taking shots of the large white spider when this little one crawled up on to the bigger spider. Just about missed the shot altogether when my jaw dropped open. Had never seen anything like that. I thought it was a different species of spider and was expecting all out war. When I got home, thought it might be a baby of the big one. My reading and some other people suggest the small one is a male and is the mate of the big one. Still not 100% sure which it is. Need to do more reading.
