This was one of scores of opened goldenrod galls found in the cut portion of the old field. It is remarkable how neatly the gall has been chewed in half, and the little goldenrod gall fly grub extracted from its shelter in the middle. These galls are hard, not easily cut with a sharp knife, so it is all the more interesting that squirrels and mice can chew them open so perfectly, like this one.
