Your letter to the bugman:  Dear Bugman,
I found this beautiful spider in the center of its round web. It was in a bog in the New Jersey Pine Barrens, in stand of Cedar Trees. Also growing in the area were Pitch Pine, blueberry, lichen, and a variety of wetland plants.
The spider was small, maybe about a 1/4 inch long.  I found it today, April 25th.
These are my own photos.
Thanks very much!

Dear Shawn,
Our best guess is that this is a Giant Lichen Orbweaver, Araneus bicentenarius, which is pictured here on BugGuide and here on BugGuide.  Exact identification might prove difficult because based on the time of year, your location and the size you indicate, this is probably an immature individual that will mature in the fall.  According to BugGuide, the habitat is:  “Woodlands, on trees, among lichens.”
