There is an animated movie with young teen/woman who flies/glides on some sort of a wind board? (not sure)

Anyway she is hippie like and has a connection with these huge beetle like things with many eyes that change color when they get mad.

There is also somewhat of a kingdom battle and one of them wants to resurrect these evil fire/lava demons.

Try,.
