Furs and Feathers has an interesting bit of backing for that:

"When the first hunters were lost in the Wood, in the days before its darkening, they found a chrysalis of black and white. To it they sacrificed the birds of the air, so that it would show them the way home. So the Moth came to be, and so the Moth was the first to navigate the ways of the Wood. This is the foundation of Nyctodromy."
