Congratulations to the many of you who knew that the swirls/holes that are present in forest floors, lawns and anywhere there are grubs are the work of a Striped Skunk. The swirls (or “twizzles,”as one reader called them) are created when the skunk is actively looking for food, and probes the ground with its nose. If and when it smells a protein-rich earthworm or grub (larval insect) in the ground, it digs a hole in order to retrieve it. These cone-shaped holes are dug at night, when skunks are active, and often appear after a heavy rain. This is because grubs move closer to the surface of the ground when the ground is wet, making it possible for a skunk to smell them. When the soil dries, the grubs move back down into deeper soil and skunks will no longer be able to smell them — thus, no more holes will be dug. Because many animals are eating voraciously in order to put on fat for the winter, signs of digging activity are frequently seen in the fall.
