Lycodon aulicus, commonly known as the Indian wolf snake and the common wolf snake, is a species of nonvenomous snake in the subfamily Colubrinae of the family Colubridae.

The colouration of this snake is variable. This snake is often confused with the common krait. The presence of a loreal shield can be used to distinguish it from kraits. The following is a description of various forms from Albert Günther's Reptiles of British India (1864).
Snout broad, much depressed, long, spatulate, with the upper lip swollen, and without canthus rostralis. Rostral shield very low, broad, slightly bent backwards on the upper surface of the snout; anterior frontals [= internasals] very small; posterior frontals [= prefrontals] longer than broad, much more so in adult specimens than in young ones; there is a lateral notch between the anterior and posterior frontals, in which the inner anterior angle of the loreal is received; the posterior frontals have an obtuse lateral angle corresponding to the suture between loreal...

Likely
About 50% of wildlife watchers report an Indian Wolf Snake sighting in Chattogram on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 6 reptiles we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
March
In that month about 70% of wildlife watchers report an Indian Wolf Snake in Chattogram on a given day, against about 10% in April and August–October, the lowest months. That is one of Chattogram's driest months, with about 40 mm of rain against 780 mm in July. February has too few records to rate.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Indian Wolf Snake sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 9 cities where we can rate Indian Wolf Snake sightings, Chattogram ranks 2nd at about 50%, level with the leaders once rounded. The best odds are in Lucknow (India, about 50%).
Same family: Colubridae
The closest relatives of the Indian Wolf Snake that you can see in Chattogram (family Colubridae, Colubrid Snakes) are Chequered Keelback (about 50%) and Copperhead Rat Snake (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Indian Wolf Snake is recorded against all the reptiles logged in Chattogram (9 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
