We have a Spiny Orb Weaver that has taken up residence above our front foundation shrubs (in Texas). Not only is the web large, I'm amazed that it extends up to a tree, about 7' above. Fortunately this web is out of the way and in a perfect location to catch plentiful stealth mosquitos. How does it evaluate a good spot for building? How good does it see for such evaluation? Does this mean it had to climb that tree and descend down? Mostly I'm impressed with the precision this web is being constructed. The radials are all precise. It (gender unknown) cycles around the radial threads, pulls the radial up to attach the cross thread it's currently laying, then moves to the next radial. I tried to take a picture, but it was too small and the thread too fine to be seen by my iPhone. I also wonder how spiders exist around the world that have this web building in their DNA. Are they all of common descent, (how did they spread?) or did they develop this talent independently? Btw, the web my SOW is building is much more professional than the examples below.
