Eriophora cf. ravilla
A fairly large spider that spins a new web every evening. In the morning the web is gone and they find some leaves to hide under during the day, like in the picture. They are similar in shape to what we call crab spiders in Michigan. This one has a large green patch on it's back. The size of the patch varies quite a lot between individuals.
In some bushes next to a house.
From Bug Guide.net "Generally dull brown, sometimes with white or yellow "shoulders" on the abdomen. An alternate color form, seen sometimes in males and sub-adult females, has a large yellow-green patch on top of the abdomen."
