We have a new pet of sorts this summer. It's an Orb-Weaving Spider. We first noticed it early in the summer, but you can only see it at night. Every morning, this web is gone. One of the mysteries is where the web goes. Does the spider eat it? We don't know, but the spider rebuilds it every night. It's over on the edge of the patio (You can see our giant red oak tree behind it in this picture) and I figure it's helping with the mosquitoes out there.
It's amazing to watch it weave this web every night. It patiently walks around and around, spinning the web as it goes. It's incredible engineering and design when you think about it. (Clearly this arachnid was designed!) It's interesting that it doesn't get caught in its own web.
