With luck
About 10% of wildlife watchers report a Black-Splashed Elf sighting in Durban on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 132nd most-seen of the 401 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.
October and December–May
In those months about 10% of wildlife watchers report a Black-Splashed Elf in Durban on a given day, against under 5% in June–September and November, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Black-Splashed Elf sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Durban, in our data
Durban is the only city on Wallace's Line with enough records to rate Black-Splashed Elf sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Libellulidae
The closest relatives of the Black-Splashed Elf that you can see in Durban (family Libellulidae, Skimmers) are Julia Skimmer (about 30%), Lucia Widow (about 20%) and Red-Veined Dropwing (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-Splashed Elf is recorded against all the insects logged in Durban (19 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.
