With luck
About 10% of wildlife watchers report a Stephanorrhynchus tuberosus sighting in Egmont National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 69th most-seen of the 191 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January–February and September
In those months about 20% of wildlife watchers report a Stephanorrhynchus tuberosus in Egmont National Park on a given day, against under 5% in March–August and October–November, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Stephanorrhynchus tuberosus sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Egmont National Park, in our data
Egmont National Park is the only park on Wallace's Line with enough records to rate Stephanorrhynchus tuberosus sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Stephanorrhynchus tuberosus is recorded against all the insects logged in Egmont National Park (11 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.
