Possible
About 20% of wildlife watchers report an Issoria baumanni sighting in Bwindi Impenetrable National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 38 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.
July
In that month about 30% of wildlife watchers report an Issoria baumanni in Bwindi Impenetrable National Park on a given day, against under 5% in March–June, August and October–December, the lowest months. That is one of Bwindi Impenetrable National Park's driest months, with about 100 mm of rain against 320 mm in October.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Issoria baumanni sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Bwindi Impenetrable National Park, in our data
Bwindi Impenetrable National Park is the only park on Wallace's Line with enough records to rate Issoria baumanni sightings: about 20% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Issoria baumanni is recorded against all the insects logged in Bwindi Impenetrable 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.
