Generally, towards evening, the spider consumes the old web, rests for about an hour, then spins a new web in the same general location. Thus, the webs of orb-weavers are generally free of the accumulation of detritus common to other species, such as black widow spiders. Some orb-weavers do not build webs at all.
The average toughness of the fibres is 350 MJ/m 3, and some are up to 520 MJ/m 3, making the silk twice as tough as any other spider silk known. [8] The web of Darwin's bark spider is remarkable in that it is not only the longest spanning web ever observed, but is the largest orb web ever seen, at an area of up to 2.8 square metres (30 sq ft).
