Arachnids

I'm not sure what an abundance of spiders signifies for the upcoming winter, but I have never seen so many spider webs, both outside and inside. And they seem to materialize in no time: I have to clean the corners of the windows, and the windowsills, daily. There are webs where I've never seen them, even between items that are moved and used frequently: say, inside the kibble bag, and between the faucet and the dish drainer.
Outside I've seen oversized webs hanging down from telephone wires: how are they anchored?
And I spotted these pretty webs near Doe Run at sunup one recent misty day.
