Arachnophobes: Web Warning
The metroplex found itself festooned with spiderwebs this morning. Apparently, a mass hatching of spiders triggered by the cooler weather sent up their ballooning tethers…and went nowhere. In the dead-calm air, the threads tangled into bundles and eventually draped over trees, lampposts, buildings–even hanging in the middle of the street. Here’s a better picture of one of the masses of web. (Arachnophobes, if you ignored the warning: try not to think about how many almost invisibly tiny spiders it took to make enough silk to leave skeins like that all over a big, sprawling city.)
Also, new research into spider ballooning indicates they they actually generate lift using the electrostatic charge on the thread, rather than relying on updrafts. That might explain how the strands were able to rise high enough to get all over everything in the absence of significant wind.
I’m not really a fan of spiders myself, but I found all this pretty cool.
