Possible
About 20% of wildlife watchers report an African Line Blue sighting in Lusaka on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 30th most-seen of the 72 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
January
In that month about 40% of wildlife watchers report an African Line Blue in Lusaka on a given day, against under 5% in April–June, August and October, the lowest months. That is one of Lusaka's wettest months, with about 210 mm of rain against almost none in August.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most African Line Blue sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Lusaka, in our data
Lusaka is the only city on Wallace's Line with enough records to rate African Line Blue sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Lycaenidae
The closest relatives of the African Line Blue that you can see in Lusaka (family Lycaenidae, Gossamer-winged Butterflies) are African Grass Blue (about 90%), Lemolea Harvester (about 60%) and Geranium Bronze (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the African Line Blue is recorded against all the insects logged in Lusaka (12 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.
