They follow all of Luna Girl's orders and attempt to complete them to the best of their ability. The moths love her, despite her often mean and verbally-abusive treatment to them.
The moths are small and white in appearance. They are each about the size of Luna Girl's fingers but can be large when flying in groups.
- Even though Luna Girl often treats them quite poorly in some episodes, they still appear to care for her.
- They almost left her in "Catboy and the Butterfly Brigade" after a large amount of criticism and mistreatment, but went back to Luna Girl when she became sad about it.
- They may be able to partly speak in English, as they sang the "We can't think of a rhyme!" portion of the PJ Masks' theme song in "Catboy's Tricky Ticket".
- They are shown to be great painters in "Catboy's Flying Fiasco".
- They made noise for the first time when Catboy used his Super Cat Ears in "Owlette and the Giving Owl".
- One of them gains a new appearance and a name: Motsuki.
- She is also the first moth to transform into a humanoid in "Moth on the Moon."
