Thailand’s Black and White Snakes

Malayan Krait (Blue Krait) from Southern Thailand. Common, dangerous, deadly, and size is usually about 1 meter long.
Adult Malayan (Blue) Krait from Thailand. These are common across much of the country, and have a very potent neurotoxic venom. Contact with this krait should be avoided.

One of the biggest problems (and dangers) of herping in Thailand is not knowing which snake you’re looking at. There are many snakes which look close enough to each other and can be misidentified. The black and white snakes are probably the most difficult to distinguish because when juvenile, they can look quite similar in appearance.

Black and White Snakes (as adults or juveniles)

  • Butler’s Wolf Snake – Lycodon butleri
  • Dark (Dusky) Wolf Snake – Lepturophis albofuscus
  • Laotian Wolf Snake – Lycodon laoensis
  • Malayan Bridle Snake – Dryocalamus subannulatus (usually brown and white or brown
  • Malayan Krait (Blue Krait) – Bungarus candidus*
  • Malayan (White) Banded Wolf Snake – Lycodon subcinctus
  • Many-banded Krait – Bungarus multicinctus*

Deadly snakes in the list above are marked with an asterisk (*).
