Last Saturday was warm and rainy, and I took a walk on the forested hillside of the arboretum. I wanted to be a little more sheltered from the wind and rain and to listen to the magical, orchestral sound of the rain falling through the canopy. As I paused on the trail soaking it up, I noticed, what appeared to be, small earthworms crawling around on a tree. They ranged in height on the tree from near the base up to about eight feet. They were all small and thin. I took this video to show you and also to let you hear the rain that was pouring down. Along the trail, I saw them on big-leaf maples, Douglas firs, and incense cedars. The ground underneath these big trees was fairly sheltered and had not become saturated with water, forcing the worms to the surface. Why were they crawling around on the trunks of these trees? There are so many mysteries to be encountered in nature every day.
