About 20% of wildlife watchers report an Apple-Green Swallowtail sighting in Arusha National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 13 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 80%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Apple-Green Swallowtail is recorded against all the insects logged in Arusha National Park (7 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.
