This is the web of the basilica spider--Mecynogea lemniscata. The web itself is the interesting thing. It's a big complex supporting the central dome where the spider stays. Above it are a string of egg cases hung vertically from the lemniscus--a horizontal line composed of many fibers and very strong. At the end of the season, or when the spider wants another web, it severs the lower lines holding the dome in tension, and the dome just springs up over the eggs cases. The spider wraps the eggs cases with the defunct dome web and deserts the web.
