The glasswing butterfly is quite the sight to see —  not because its wings are colorful, but rather transparent as glass.

Take a closer look in this captivating, short video by Deep Look/PBS, which zooms in on the life cycle of the glasswing butterfly, Greta oto, as it forms the invisible wing.

The video features Aaron Pomerantz, a graduate student in MBL Director Nipam Patel’s lab, who not only studies how the glasswing butterfly develops its see-through wings – he videotaped most of the segment himself!
