Boaedon capensis, the Cape house snake, also known as the brown house snake, is a species of lamprophiid from Botswana, South Africa (from KwaZulu-Natal all the way through to the Western Cape), Mozambique, Zambia and Zimbabwe. They are a non-venomous lamprophiid. This species was previously grouped in the genus Lamprophis but is regrouped with the genus Boaedon.
Cape house snakes are usually dark brown on top, but the colour varies greatly from almost black through brown to olive green. The stripes that stretch from the rostral scale through the eye to the back of the head are very strong, thick, and bold. This species may have a lateral stripe running down the flanks, often resembling the links of a chain. They also sometimes have lateral stripes running along either side of the spine. Linking lines between the lateral striping is not uncommon. These body markings tend to be a paler brown/cream in colour on top of the often dark, chocolate-brown base tones. These markings normally fade two-thirds of the way down the body until only the base colour remains, but there are exceptions to the rule. Individuals without pattern are often found in the wild.

Possible
About 20% of wildlife watchers report a Brown House Snake sighting in Johannesburg on a given day, based on 36 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 15 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 80%, if each day is a fresh chance.
January–February and November
In those months about 30% of wildlife watchers report a Brown House Snake in Johannesburg on a given day, against under 5% in March and August, the lowest months. Those are among Johannesburg's wettest months, with about 100 mm of rain a month against almost none in July.
Between 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Brown House Snake sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.

Same family: Lamprophiidae

GBIF citizen-science records
It is estimated from how often the Brown House Snake is recorded against all the reptiles logged in Johannesburg (36 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.
