Lycodon rufozonatus is a species of snake in the family Colubridae. The species is native to East Asia. It is medium-sized, nocturnal, and is considered non-venomous. The subspecific name, walli, is in honor of British herpetologist Frank Wall. Lycodon rufozonatus typically grows to a total length (including tail) of around 70 centimetres (28 in), reaching up to 130 cm (51 in) in extreme cases. The head is long and relatively flat, and somewhat separate from the neck. The medium-sized eyes bulge slightly and have vertical pupils. The ventral scales have a strong keel, while the dorsal scales are only faintly keeled; the scale count is typically 17:17:15, but can be up to 21:19:17.
Lycodon rufozonatus is found across a large part of East Asia, from the Korean Peninsula in the north (and extending just into easternmost Russia) to northern Laos and Vietnam in the south; the bulk of its range in found in eastern China. The continental populations are all placed... Wikipedia →

With luck
About 10% of wildlife watchers report a Red-banded Snake sighting in Shanghai on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 6 reptiles we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Red-banded Snake in Shanghai on a given day, against under 5% in March, September and November–January, the lowest months. That is one of Shanghai's wettest months, with about 200 mm of rain against 55 mm in December.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Red-banded Snake sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 12
Of the 12 cities where we can rate Red-banded Snake sightings, Shanghai ranks 9th at about 10%. The best odds are in Hefei (China, about 40%), Busan (South Korea, about 30%) and Wuhan (China, about 20%).
GBIF citizen-science records
It is estimated from how often the Red-banded Snake is recorded against all the reptiles logged in Shanghai (11 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.
