With luck
About 10% of wildlife watchers report a Microrca bistrialis sighting in Main Ridge Forest Reserve on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 296th most-seen of the 346 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.
March
In that month about 30% of wildlife watchers report a Microrca bistrialis in Main Ridge Forest Reserve on a given day, against under 5% in April to November, the lowest months. That is one of Main Ridge Forest Reserve's driest months, with about 65 mm of rain against 230 mm in October.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Microrca bistrialis 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 Microrca bistrialis sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Microrca bistrialis is recorded against all the insects logged in Main Ridge Forest Reserve (5 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.
