The black spider is an old pattern popularised anew in the UK by Tom Ivens some time during the late 60's or early 70's (if memory serves) as a pattern to imitate snails particularly in reservoirs, which became known as the Black & Peacock Spider.
While using the fly once, I remember catching a rainbow so full of snails it's belly looked 'lumpy', though it managed to find room for one more.
I recommend the little hard-cover book featured, although out of print for some time; last printing 2004. I found my copy on-line. Originally published and edited by Trout & Salmon magazine, UK.
