New Year Gift ( Yellow Speckled Wolf Snake)

This day I got a call from a friend asking me if I would collect a snake they have captured or would they kill it. And I certainly told him to keep the snake for me. Then I asked him about the description of the snake and came to know that it is a green snake with spots on it. I was not sure which snake it was from the description but as it is not similar to any venomous snakes found here locally, I told him, “it is probably a non-venomous snake but still don’t touch it.”

This conversation happened in the morning and I was told to pick up the snake in the evening. The whole day I was thinking about the snake but could not decide what it could be and in the evening when I received the snake, reality exceeded all my expectations! It was a small snake, approximately 12”-14” long with brownish green back and white belly. Moreover it had two yellow spots on each scale. And I shouted in joy, “it’s a yellow-speckled wolf snake!!!!” whenever I saw its photo in books and various online groups, I wished to see one in real life but its distribution is so limited that I never thought I would see one ever, that too in my hometown. It was 2nd January and all I could think was that this was the best new year gift ever.

Yellow Speckled Wolf Snake ( Lycodon jara ) is a non-venomous snake found from West Bengal, Arunachal Pradesh and Ganjam district of Orissa in India and also from Nepal and Bangladesh. The maximum length recorded is 22”. It’s a smooth scaled, slender bodied snake. The head is slightly broader than the neck like all other wolf snakes. The upper side varies from glossy brown to purplish black. Belly side is white in color. Almost all the scales on its back have two yellow spots on them and thus the name. Sometime the spots are white in color. Very little is known about this snake. Only that it is a nocturnal snake and it eats geckos.
From my personal observation I found that this snake prefers corners and crevices than open place. Though it is a nocturnal snake, given a choice to stay between a dark open place and a bright corner, it feels more secure in the corner. It also hides its head slightly under its body coil like a few other wolf snakes. “And unlike the Common Wolf Snake, not tempermental and usually does not bite when handled.” Though the previous line was written for a few other wolf snakes like Barred Wolf Snake in the book ‘Snakes of India, The Field Guide’, I found it perfectly suitable for this one too.

When I released it in my own front yard, it was very quick to vanish from my eye and I am sure not to see it again ever though it is just in front of my house. Snakes have evolved to stay hidden so good that we often don’t realize how many snakes are there around us. That is infact in the benefit of both of us. Otherwise we would have killed all the snakes if we had the chance, or atleast that is the mentality of many of us. But it is good to know that people are changing. Thank you Utpal Das for this wonderful new year gift.

how to differentiate between common Indian Krait and common Wolf snake

Yesterday when I was out in the evening, suddenly I got a call from home; my mother was yelling “there is a venomous snake in the house, come quick…”. So, I hurried back home only to find out that a common wolf snake was climbing the corner of our door. Everyone believed that it’s a very venomous snake and I should kill it instantly. After talking with them I found out that all they were talking about is of common Indian Krait. It took me a sweating discussion to convince them that it is not a venomous snake; it’s a non-venomous common Wolf snake. Actually people often mistake these two snakes for each other.
COMMON INDIAN KRAIT

COMMON WOLF SNAKE

But is it that much difficult to identify them separately? Absolutely not. One can distinguish a venomous snake from a non-venomous one by opening its mouth and checking the fangs, though its not an easy process. But there is a catch, common Wolf snake’s front teeth of upper and lower jaws are larger which are often mistaken for fangs. So finally the question comes to, ‘how does a lay person identify a non-venomous common Wolf snake from a venomous common Krait snake??

  • Firstly, there is a size difference. Adult common Wolf snake can be upto 2.5ft of length but specimens larger than 2 ft are rare. Whereas an adult common Krait snake can be upto 6ft long but the average is 3.5ft. Then the fact arises that a common Wolf snake can be mistaken for a sub-adult common Krait snake. So we come to next difference.

  • The white stripes of a common Wolf snake are a bit broader than the common Krait snakes and also the stripes are bordered with somewhat darker scales than the body. Moreover the stripes of common Krait snakes are paired, whereas common Wolf snakes’ stripes are not paired. The most prominent difference from the point of stripes is that common Wolf snakes have got a broad stripe on their neck which is absent in common Krait snakes.


  • Thirdly, the body shape of common Krait snake is somewhat triangular and it is ridged along its vertebral line. In common Wolf snake, the body is roundish and there is no ridge formation.


  • Lastly, the scales of common Krait snake along its vertebral line are hexagonal, means six-sided, and larger which differentiates these from other body scales (in the picture it is actually a banded krait, but this feature is common in all type of kraits.). But we don’t see such phenomena in case of common Wolf snakes. All the scales on its back are of same size and shape. And this one is the most important one.


So by following these simple points one can easily distinguish between the common Wolf and common Krait and I won’t have to hurried back home for a false alarm. ;-)
