Sept 13, 2008:Nephila mating (and skippers also)

This was quite an interesting session. The female Nephila had moved her web closer to the ground so that she was eye-level with me. The male was actively engaged in love making. This amounts to weaving a mat or carpet of silk over the female's abdomen and cephalothorax. The milky appearance that you see near her 4th legs is the carpet and the male is just behind the leg.
