Possible
About 20% of wildlife watchers report a Madagascar Diadem sighting in Ranomafana National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 32nd most-seen of the 68 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September
In that month about 50% of wildlife watchers report a Madagascar Diadem in Ranomafana National Park on a given day, against under 5% in February–May, July and October–December, the lowest months. That is one of Ranomafana National Park's driest months, with about 80 mm of rain against 450 mm in January.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Madagascar Diadem sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Madagascar Diadem sightings, Ranomafana National Park ranks 2nd at about 20%. The best odds are in Mantadia National Park (Madagascar, about 30%).
GBIF citizen-science records
It is estimated from how often the Madagascar Diadem is recorded against all the insects logged in Ranomafana National Park (8 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.
