On the other hand, up in the hill country I’ve walked paths with webs like these you show here strung all the way across. Some can be three or four feet wide. Amazing!
I imagine that each species of spider has adapted it’s construction to its own unique habitat and hunting strategy. It could be quite a study if one covered them all. I also suspect that the webs might change over the course of a summer, fine strings early on, then tougher ones as grasshoppers and larger insects enter the scene later in summer. One of the things, were I to have several more lifetimes, I might try to quantify.
Yes, they must be amazingly strong. The strands of these were very fine too, so fine in fact that even with the mist on them, autofocus would not work, and with all but one of these photos I had to use flash to get the web to show up at all.
