With luck
About 10% of wildlife watchers report a Swamp Bluet sighting in Pretoria on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 162nd most-seen of the 274 insects 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.
January–March, May and November
In those months about 10% of wildlife watchers report a Swamp Bluet in Pretoria on a given day, against under 5% in April, June–October and December, the lowest months. Those are among Pretoria's wettest months, with about 75 mm of rain a month against almost none in July.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Swamp Bluet sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Swamp Bluet sightings, Pretoria ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Johannesburg (South Africa, about 10%).
Same family: Coenagrionidae
The closest relatives of the Swamp Bluet that you can see in Pretoria (family Coenagrionidae, Narrow-winged Damselflies) are Salisbury Sprite (about 10%), Common Bluetail (about 10%) and Powder-Faced Sprite (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Swamp Bluet is recorded against all the insects logged in Pretoria (8 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.
