Bothrops diporus, also known in Portuguese as Bocuda, Cabeça-de-Capanga, Jararaca-do-Chaco, Jararaca-do-Rabo-Branco, Jararaca-Pintada, Jararaca-Pintada-Argentina and Jararaca-Pintada-do-Sul, is a species of viper from the forests of Argentina, Brazil, Paraguay and Bolivia. As with all vipers, it is venomous.
Bothrops diporus is identifiable by its dark pattern, which consists mainly of fused dark triangular markings on a lighter base colour, similar to that of B. ayerbei with the two rounded dark blotches at the base of each triangle.
Bothrops diporus have been sighted at a length of around 70–80 cm (28–31 in). Bothrops diporus has been sighted partaking in ophiophagy of Chironius maculoventris and Epictia albipuncta, however it is known for its largely mammalian diet, including rodents, frogs and lizards. Bothrops diporus is one of the main causes of snakebite in Argentina: between 1960 and 1975, according to Esteso (1985), 80% of the approximately 500 cases reported each year were attributed to this species.
Bothrops diporus has been found in the Vermejo River region, on the boundary of Paraguay and Argentina. Wikipedia →

With luck
About 10% of wildlife watchers report a Painted Lancehead sighting in Iguaçu National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 17 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.
May
In that month about 20% of wildlife watchers report a Painted Lancehead in Iguaçu National Park on a given day, against under 5% in January–April and June–September, the lowest months.

GBIF citizen-science records
It is estimated from how often the Painted Lancehead is recorded against all the reptiles logged in Iguaçu National Park (6 verified sightings from 2019 to 2026), 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.
