Byblia ilithyia, the spotted joker or joker, is a species of nymphalid butterfly found in parts of Africa and Asia. The male has the upperwings of a deep rich orange. The forewing has the costa broadly black until nearly the apex. The cell has three narrow short black bands, the inner and outer not reaching the median vein. An irregular black spot from dorsum to vein 4, continues very narrowly along that vein to meet an oblique irregular band from just beyond the middle of the costa. A postdiscal broad transverse black band from dorsum to vein 4, with the portions of the veins beyond it defined in black. The apex of the wing beyond the broad black edging to the costal border has its upper margin and the terminal portions of the veins defined in black; finally a narrow terminal band. The hindwing has an elongate black sub-costal patch near base, continued posteriorly across the cell by an inner and an outer series of small transverse spots; a complete broad black postdiscal band with the portions of the veins beyond it lined with black, and a narrow black terminal band as on the forewing. Cilia of forewings and hindwings white, alternated... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Spotted Joker is recorded against all the insects logged in Hluhluwe-Imfolozi Park (15 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.
