I happened to notice this large, tan, sort of furry spider hanging out in the center of his beautiful orb web yesterday. So I snapped his photo which I am sending for you to see. What is amazing is that when I woke up this morning to see him, there was nothing there. Not one strand of web left behind. Do spiders eat their webs when they move to a new place? I am glad I took this photo so I know I am not having a senior moment.

Some orb weaver garden spiders eat their webs. Spider web silk is made from protein. By eating the old webs, spiders can recycle the silk/protein and use it to make new webs. So in a sense, they can pick up (eat) their old webs and move (re-spin) them. Clever creatures, aren’t they? /Gary
