Just consulted my book on "British Spiders": ARANEIDAE or orb-weavers contain some 33 species in 15 genera. Webs are spun horizontally in short grass, long grass, gardens, woodlands, eaves of buildings and across farm gates. Insects are trapped in the web, then spun in silk and eaten.
Mating involves a complex series of vibration and jerking of the female's web by the male who may mate with several females during the summer. Each time he risks losing legs or palps until, finally, he cannot escape and at the last time of mating is devoured. Eggs are laid after mating and take two or three years to reach maturity and complete their life cycle.
I bet you all wanted to know that!!!!
As to new webs everyday, no mention in the book and it's not something I've noticed in the garden spiders at home.
