Zizeeria knysna, the dark grass blue or African grass blue, is a species of blue butterfly (Lycaenidae) found in Africa, on Cyprus and the Iberian Peninsula. Sometimes mistakenly called Zizeeria lysimon (Hübner), that species name is invalid as it is preoccupied by Papilio lisimon Stoll, [1790], a butterfly in the family Riodinidae.
The wingspan is 18–23 mm for males and 21–26 mm for females. The butterfly flies nearly year-round. The larvae feed on Medicago, Melilotus, Acanthyllis, Armeria delicatula, Polygonum equisetiforme, Tribulus terrestris and Oxalis.

Possible
About 20% of wildlife watchers report an African Grass Blue sighting in Gorongosa National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 27th most-seen of the 41 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
October
In that month about 50% of wildlife watchers report an African Grass Blue in Gorongosa National Park on a given day, against under 5% in March–April, June–September and December, the lowest months. That is one of Gorongosa National Park's driest months, with about 30 mm of rain against 210 mm in January.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most African Grass Blue sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 12
Of the 12 parks where we can rate African Grass Blue sightings, Gorongosa National Park ranks 4th at about 20%. The best odds are in South Luangwa National Park (Zambia, about 40%), Gonarezhou National Park (Zimbabwe, about 30%) and iSimangaliso Wetland Park (South Africa, about 20%).
Same order: Lepidoptera
The closest relatives of the African Grass Blue that you can see in Gorongosa National Park (order Lepidoptera, Butterflies and Moths) are Variegated Pearl (about 30%), Gold-Banded Forester (about 30%) and Sundowner Moth (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the African Grass Blue is recorded against all the insects logged in Gorongosa National Park (5 verified sightings from 2019 to 2026), 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.
