strangly i just said to my mother i thourght the smaller one was offering food to the larger one currently resting on top in the little nest that species does look alot like it just found a picture of the male and female together url:

although their web is still a bit of a mess this must be it. the markings are a bit diffrent but the pictures are much closer than i can get

thank you.
just woundering because we like these spider and they are like our pets does the female eat the male after mating?
