With luck
About 10% of wildlife watchers report an Atomotricha isogama sighting in Egmont National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 99th 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 50%, if each day is a fresh chance.
October
In that month about 30% of wildlife watchers report an Atomotricha isogama in Egmont National Park on a given day, against under 5% in February to August, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Atomotricha isogama sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen 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 Atomotricha isogama sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Oecophoridae

GBIF citizen-science records
It is estimated from how often the Atomotricha isogama is recorded against all the insects logged in Egmont 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.
