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.

Likely
About 40% of wildlife watchers report a Citrus Swallowtail sighting in Cotonou on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 9 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
July
In that month about 70% of wildlife watchers report a Citrus Swallowtail in Cotonou on a given day, against about 10% in February–April and September–October, the lowest months. That is one of Cotonou's wettest months, with about 170 mm of rain against 20 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Citrus Swallowtail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 21
Of the 21 cities where we can rate Citrus Swallowtail sightings, Cotonou ranks 3rd at about 40%. The best odds are in Accra (Ghana, about 50%) and Dar es-Salaam (Tanzania, about 40%).

GBIF citizen-science records
It is estimated from how often the Citrus Swallowtail is recorded against all the insects logged in Cotonou (15 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.
