Although it is known that a small percentage of crop circles have been hoaxes,there are many more circles that remain unexplainable by science.
I stumbled upon this image. Apparently on Aug. 8th "09" , there was discovered the lagest known crop circle depicting the metamorphosis of the Caterpillar into a Butterfly.
The photo's look genuine,but the only thing that make me somewhat skeptical is that there has not been any "official" media coverage of this piece of art.
Here is one page i found regarding the image...not sure how reliable this sight is,i also did a google search an found some other sights, but nothing official.
None the less it is a beauitful piece of art.....to think it wasn't a hoax would be exciting.
