The twin-barred tree snake (Chrysopelea pelias) is a species of snake found in Southeast Asia. It is also called the banded flying snake. It can glide, as with all species of its genus Chrysopelea, by stretching the body into a flattened strip using its ribs. It is mostly found in moist forests and can cover a horizontal distance of about 100 metres in a glide from the top of a tree. It is an oviparous snake.
