A potential loophole came to mind when thinking of an answer to a question regarding Rita Skeeter and the Marauder's Map.
Rita is an animagus whose form is that of a beetle. She often uses this form to eavesdrop on others in her line of work, and would likely have used it in the school. Beetles are known to typically have flight and enjoy clinging to walls. The Marauder's Map shows the footprints of people on the school grounds.
Would it show, say, a wizard transformed into a beetle in flight or clinging on the wall? Does it show any airborne targets in the books or movies?
