With luck
About 10% of wildlife watchers report a Megarthria peterseni 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 40% of wildlife watchers report a Megarthria peterseni in Main Ridge Forest Reserve on a given day, against under 5% in January–February and April–November, the lowest months.

GBIF citizen-science records
It is estimated from how often the Megarthria peterseni 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.
