Rare
Under 5% of wildlife watchers report a Glitter Silverline sighting in Durban on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 310th most-seen of the 401 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April
In that month about 10% of wildlife watchers report a Glitter Silverline in Durban on a given day, against under 5% in May to March, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Glitter Silverline 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 Glitter Silverline sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Lycaenidae
The closest relatives of the Glitter Silverline that you can see in Durban (family Lycaenidae, Gossamer-winged Butterflies) are African Grass Blue (about 20%), Bush Bronze (about 10%) and Common Hairstreak (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Glitter Silverline is recorded against all the insects logged in Durban (6 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.
