Twin-spotted wolf snake

3-Non Venomous

Snake Type:

Common Name: Twin-spotted wolf snake
Odia Name: _______
Zoological Name: Lycodon jara

Neonate – 177 mm, Adults – 275 mm, Maximum – 550 mm. (The collarless L. jara is not found in Odisha; we put it here so that people can compare it with L. odishii containing a white collar in hatchlings which turns to yellowish in adult).
Identification: Glossy greyish or brownish black colour in neonates, which turns glossy olive green or purplish black above in adult. Two tiny spots are present on each scale of the body; the twin spots are white colour in neonates which turns to golden yellow in adults. No collar is observed in neonates to adults.

Controversy: Although, many people think young/juvenile of L. jara contains a yellow/white collar, but in reality, juveniles and sub-adult specimens were reported collarless. Three juveniles, i.e. 190 mm (Hussain & Roy 1993:113), 200 mm R/NRC/41 (Bahuguna & Bhutia 2010:37), 220 mm (Shafi et al. 2020:107); and two sub-adults i.e. 240 mm ZSI–8012 (Chaudhuri et al. 2015:97), and 250 mm R/NRC/51 (Bahuguna & Bhutia 2010:37) all are collarless, and published in reputed journals. Furthermore, 4 neonates (177 – 180 mm) of L. jara are prominently without collar. These 9 young specimens, i.e. 4 neonates (177-180 mm), 3 juveniles (190 mm, 200 mm, 220 mm), and 2 sub-adults (240 mm, 250 mm) prove that L. jara has no collar in the younger stages. On the other hand, the specimens of L. odishii with yellowish collar that laid eggs are definitely adults; the white collar is white in the hatchlings which turned to yellowish in adults in L. odishii. Accepting the ‘young has collar in L. jara’ hypothesis is to treat a mother (collared snake that laid eggs, i.e. L. odishii) as a juvenile!

We leave it to the public; they are the best judges. 🙏
