Rare
Under 5% of wildlife watchers report a Swamp Bluet sighting in Cape Town on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 127th most-seen of the 311 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–April, October and December
In those months about 10% of wildlife watchers report a Swamp Bluet in Cape Town on a given day, against under 5% in January, May–September and November, the lowest months. Those are among Cape Town's driest months, with about 30 mm of rain a month against 140 mm in June.
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.
4th of 4
Of the 4 cities where we can rate Swamp Bluet sightings, Cape Town ranks 4th at under 5%. The best odds are in Johannesburg (South Africa, about 10%), Pretoria (South Africa, about 10%) and Durban (South Africa, about 10%).
Same family: Coenagrionidae
The closest relatives of the Swamp Bluet that you can see in Cape Town (family Coenagrionidae, Narrow-winged Damselflies) are Common Bluetail (about 20%) and Common Citril (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 Cape Town (28 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.
