Some of the birch trees here in Maine seem to be infested with a pest that eats the leaves, creating interesting patterns. As we walked through a forested area by a lake, I kept seeing the fallen leaves on the forest floor, each with a pattern more intricate than the last. Although it is likely harmful to the trees, I still thought they looked looked like delicate filigree jewelry. I own a pair of gold, leaf shaped filigree earrings and these leaves were quite similar to my earrings. The red maple leaves were not affected by the chewing pest and they made a lovely background for the forest filigree.
