Lycodon striatus is found in Afghanistan, India (Andhra Pradesh, Tamil Nadu, Gujarat, Karnataka, Madhya Pradesh, Maharashtra, Punjab and Uttar Pradesh), eastern and north-eastern Iran, Nepal, Pakistan, Sri Lanka, western Tajikistan, southern Turkmenistan (Kopet Dagh) and Uzbekistan.
Lycodon striatus is dark brown or black above, with white transverse spots or crossbands, which are widely separated anteriorly. The sides are lineolated with white, with a black spot corresponding to each white crossband. The upper lip and ventrum are uniform white (coloration in alcohol).

The head is only slightly distinct from the neck, and the snout is flattened. There are 8 upper labials, the first and second contacting the nasal scale. Lycodon striatus was first described in 1802 by George Shaw, as Coluber striatus; its type locality was "Vizagapatam and Hyderabad... Wikipedia →

Possible
About 30% of wildlife watchers report a Barred Wolf Snake sighting in Lucknow on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 5th most-seen of the 9 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
February
In that month about 60% of wildlife watchers report a Barred Wolf Snake in Lucknow on a given day, against under 5% in May, the lowest month. That is one of Lucknow's driest months, with about 20 mm of rain against 320 mm in July.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Barred Wolf Snake sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Lucknow, in our data
Lucknow is the only city on Wallace's Line with enough records to rate Barred Wolf Snake sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Barred Wolf Snake is recorded against all the reptiles logged in Lucknow (7 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.
