This little friend turned up on my front porch a couple weeks ago, and it really put my camera to the test because when I call it little I mean tiny!  But look at the coloration on it - what a beautiful creature!  Leucage venusta is an orb weaver, and given my Google Images research, mine is a youngin so it should grow larger with time.  The fourth photo was taken one week after the first three photos and I think perceptible growth can be seen even in that time.
