That could be a good name for the species.
Vixen fairies seem to be a fairly old invention by the way, I have found some even in furry art from the early 1990s. I guess the nature of foxes makes them the ideal choice for faeries. As for their life cycle I haven't asked her, silly me. I can only imagine how cute the caterpillar of such a creature could be (or maybe it's the opposite and it is utterly ugly). I'll need to draw that if I can get the information and turns out they are actually born as caterpillars.
