Forewing above at most with two blue submarginal spots in cellules 7 and 8; rarely in the female with several yellow ones; the blue (male) or greenish (female) median band is 2–7 mm broad at the hindmargin of the forewing and 4–12 mm in the middle of the hindwing, and is only a little widened posteriorly; the spot in cellule 2 of the hindwing does not completely cover the base of the cellule and the narrow spot in cellule lc does not reach the cell; forewing beneath almost always entirely without submarginal spots. [Nominate] Median band of the forewing above well developed, the spots of cellules 2—4 obliquely cut off distally; the discal spot in cellule 2 of the hindwing is very long and produced farther towards the anal angle than the spot in cellule 1 c. Sierra Leone to Angola and Uganda. — lyaeus Dbl. The median band narrower, but complete; the spot in cellule 2 of the hindwing is... Wikipedia →

With luck
About 10% of wildlife watchers report a Narrow Green-Banded Swallowtail sighting in Kampala on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 22nd most-seen of the 42 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.
May
In that month about 30% of wildlife watchers report a Narrow Green-Banded Swallowtail in Kampala on a given day, against under 5% in February–March, August and October–December, the lowest months.

GBIF citizen-science records
It is estimated from how often the Narrow Green-Banded Swallowtail is recorded against all the insects logged in Kampala (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.
