From Ghibli short "Water Spider Monmom" it tells about a water spider falling in love with a female water strider who is afraid at firts but builds the connection with him. The Japanese animation makes this spider more appealing to watch. (look up google for images cause i can't copy and paste anymore)
Another animation is from a remake of the book Charlotte's Web in a 3D CGI Movie using ofcourse realistic animal characters including Charlotte the spider.
We all know the story of one female spider helping a yong pig from impending pig slaughter by using her webspinning talents. Her design is a very realistic spider. The model was mostly done seperatly then the hair must of been added last to match the textile. (link)
