Twin-barred tree snake

Chrysopelea pelias, Carolus Linnaeus, 1758

(In Thai: งูดอกหมากแดง (ngu khieow dokmak daeng))

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.

Chrysopelea pelias has an overlapping range with the paradise tree snake (Chrysopelea paradisi) in Malaysia, Singapore, Borneo and Indonesia. However, Chrysopelea pelias is not nearly as common as the paradise tree snake.


The twin-barred tree snake is found in

Thailand, Malaysia (Malaya, Penang Island, Pulau Tioman, and East Malaysia), Indonesia (Bangka, Java, Mentawai Archipelago, Nako, Natuna Archipelago, Nias, Riau Archipelago, Sumatra, Borneo); Brunei Darussalam; Burma and Singapore.
