Duskwings

From Mylegokingdom

Duskwings are large black and clear insects in the skies above The Molten Plain. They come out only during the dusk and night. By dawn, they are hiding in burrows made around the Rock Mite Ruins. Even though they look fearsome, they only eat the lichen that grows rarely in their habitat. They have a black body, and head, with clear wings.
