Borbo lugens, the lesser horned swift or lesser horned skipper, is a butterfly of the family Hesperiidae. It is found in eastern Africa and South Africa. The habitat consists of grassy clearings in dense woodland and forests.
The wingspan is 30–35 mm for males and 36–38 mm for females. Adults are on wing year-round, but are more common from October to May in southern Africa. The larvae feed on Ehrharta erecta, Setaria sulcata, Setaria megaphylla, Panicum (including Panicum deustrum), Stipa and Pennisetum species. Wikipedia →

Rare
Under 5% of wildlife watchers report a Lesser-Horned Swift sighting in Durban on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 205th 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 30%, if each day is a fresh chance.
February, April–June and August
In those months about 10% of wildlife watchers report a Lesser-Horned Swift in Durban on a given day, against under 5% in March, July and September–January, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Lesser-Horned Swift 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 Lesser-Horned Swift sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Lesser-Horned Swift is recorded against all the insects logged in Durban (10 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.
