Possible
About 20% of wildlife watchers report an Erucius apicalis sighting in Gunung Leuser National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 103 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.
March
In that month about 40% of wildlife watchers report an Erucius apicalis in Gunung Leuser National Park on a given day, against under 5% in February, June, August and October–November, the lowest months. That is one of Gunung Leuser National Park's driest months, with about 180 mm of rain against 700 mm in September.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Erucius apicalis 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 Gunung Leuser National Park, in our data
Gunung Leuser National Park is the only park on Wallace's Line with enough records to rate Erucius apicalis sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Erucius apicalis is recorded against all the insects logged in Gunung Leuser National Park (15 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.
