Hypoponera punctatissima, or Roger's ant, is a species of Ponerine ant native to Africa but now found worldwide as a tramp species. The ant is hypothesized to have spread so effectively due to humanity's use of horses as draft animals. The ant is closely related to Hypoponera ergatandria and bears several similarities, such as colony size and appearance.
Hypoponera punctatissima is a tramp species that has invaded many countries past its native range, where it resides in heated buildings, and outdoor heated habitats such as animal waste and fermenting waste. The ant is considered native in the Gulf of Guinea, Kenya, Uganda, Rwanda, Tanzania and Kenya. The ant is also native to much of southern Africa, with a native presence in Angola, Zambia, Mozambique, Botswana and South Africa. The species range also extends north to include Egypt, Sudan, Ethiopia, Central African Republic and the DRC.
Hypoponera punctatissima is considered invasive in much of Western Europe, some of the southern U.S.A states and California, much of the Middle East, the Yucatán peninsula, Panama and Venezuela. The ant retains an invasive presence in New Zealand, North Australia and... Wikipedia →

Rare
Under 5% of wildlife watchers report a Roger's Crypt Ant sighting in Bengaluru on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 268th most-seen of the 477 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February–March, September and December
In those months about 10% of wildlife watchers report a Roger's Crypt Ant in Bengaluru on a given day, against under 5% in January, April–August and October–November, the lowest months.

GBIF citizen-science records
It is estimated from how often the Roger's Crypt Ant is recorded against all the insects logged in Bengaluru (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.
