Possible
About 20% of wildlife watchers report a Rosema demorsa sighting in Main Ridge Forest Reserve on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 145th most-seen of the 346 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.

Across all the parks we cover, that three-hour window holds the most Rosema demorsa sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Main Ridge Forest Reserve, in our data
Main Ridge Forest Reserve is the only park on Wallace's Line with enough records to rate Rosema demorsa sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Rosema demorsa is recorded against all the insects logged in Main Ridge Forest Reserve (10 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.
