Papilio demodocus, the citrus swallowtail or Christmas butterfly, is a swallowtail butterfly which commonly occurs over the entirety of sub-Saharan Africa, including Madagascar, besides the southern Arabian Peninsula. The caterpillars feed on various native plants of especially the family Rutaceae, but have also taken to the leaves of cultivated citrus trees.
Citrus swallowtails pass through approximately three generations per year. Female butterflies lay their eggs singly on citrus leaves. After about six days, the egg hatches into an immature larva. The immature larvae are black, yellow, and white with spikes. Their coloration provides effective camouflage, as they resemble bird droppings. They grow to a length of 10 or 15 mm before changing into mature larvae.
Mature larvae are green with white or pink markings and eyespots. They grow to a maximum length of about 45 mm. Mature caterpillars lack the camouflage of their immature state.

GBIF citizen-science records
It is estimated from how often the Citrus Swallowtail is recorded against all the insects logged in Odzala-Kokoua National Park (6 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.
