Silkwings

SilkWings are from the Wings of Fire series. they are a dragon tribe from Pantala. (a conteinent) They can be any color under the sun except for black, and they can weave silk. SilkWings undergo a metamorphosis at the dragon age of six, where they get their four wings and the ability to spin silk. In metamorphosis, they are in a cocoon of their silk color, which is usually white or silver colored. However, some SilkWings are flamesilks. They can spin flaming silk, and when they go into metamorphosis, their cocoon is fiery orange, like their silk. When they exit metamorphosis, they are immune to other flamesilks and can't be burned by it. It is unknown if this works with all kinds of fire, however.
