Rare
Under 5% of wildlife watchers report a Coastal Swordtail sighting in Kruger National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 290th most-seen of the 748 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.
September to December
In those months about 10% of wildlife watchers report a Coastal Swordtail in Kruger National Park on a given day, against under 5% in January to August, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Coastal Swordtail sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Kruger National Park, in our data
Kruger National Park is the only park on Wallace's Line with enough records to rate Coastal Swordtail sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Coastal Swordtail is recorded against all the insects logged in Kruger National Park (16 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.
