With luck
About 10% of wildlife watchers report a Navy Dropwing sighting in Durban on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 152nd 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 30%, if each day is a fresh chance.
October to March
In those months about 10% of wildlife watchers report a Navy Dropwing in Durban on a given day, against under 5% in April to September, the lowest months. Those are among Durban's wettest months, with about 180 mm of rain a month against 25 mm in June.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Navy Dropwing sightings with a recorded time, and about 9 in 10 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 Navy Dropwing sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Trithemis
The closest relatives of the Navy Dropwing that you can see in Durban (genus Trithemis, Dropwings) are Red-Veined Dropwing (about 10%) and Orange-Winged Dropwing (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Navy Dropwing is recorded against all the insects logged in Durban (17 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.
