Possible
About 30% of wildlife watchers report an Ideopsis vitrea sighting in Tangkoko Nature Reserve on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 38 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February–March and December
In those months about 40% of wildlife watchers report an Ideopsis vitrea in Tangkoko Nature Reserve on a given day, against under 5% in January and April–May, the lowest months.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Ideopsis vitrea sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Tangkoko Nature Reserve, in our data
Tangkoko Nature Reserve is the only park on Wallace's Line with enough records to rate Ideopsis vitrea sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ideopsis vitrea is recorded against all the insects logged in Tangkoko Nature Reserve (13 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.
