If two Dumbledore look more thoroughly, they would notice, the moth-chasing guy is in fact, in real danger, moth is a spiritual form of a specific magic creature called musebutterfly. They are an innocent adorable creature in original form, but their frequency of fluttering can be extremely disturbed by some strange pitch or a certain type of sound. Then all the energy in its body is going to be transferred and concentrated to fight the annoying untraceable pitch, leading to the shrink of her body.
