Around the base of the tree in my front yard, there are a circular bed of flowers. In the past week, about 1 - 2 inch wide paths with no grass have started appearing coming out from the bed of flowers into the grass. So far, the trails have appeared in two spots. One trail continues for several feet back into the grass, although grass from the sides covers it so you can't see it that well, but if you feel with your hand, it is there.
It's like the grass just stopped growing to form these trails. I have no idea what is doing it. Bugs? Mouse? Squirrel? Mole? Snake?
Here are some pictures of the trails:
