This video from the USA says about itself:
26 September 2016
These attractive male and female Marbled Orb Weavers are taking a daytime nap together. The male has attached his “mating thread” across her web and I anticipated much spider action later, but alas other than a few tosses and turns as they slept in their webs when nighttime came they did not mate for at least a few hours and I was denied the chance to see Ms. Orb Weaver partake of Mr Orb Weaver – his last meal. I may lack the patience required for this video task.
How do they reproduce?
There is little information about the mating habits of marbled orb-weavers, although they may behave similarly to other members of their genus (Araneus). Females of these species emit pheromones to attract mates. To court mates, males spin a “mating-thread” across the female’s web. The male moves towards the female across this thread, plucking and vibrating it, and the female approaches him. The male touches the front of the female’s body with his legs, stroking her, until she hangs from the mating thread. Mating takes place in late summer and males mate several times. In some species of orb-weaving spiders, females eat their mates after breeding, this includes European garden spiders, which are closely related and live in the same area. Marbled orb-weavers may also do this; however, males mate multiple times and often survive mating, so cannibalism may not be as common in this species.
