With luck
About 10% of wildlife watchers report a Holocola thalassinana sighting in Blue Mountains National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 272nd most-seen of the 789 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February and April–November
In those months about 10% of wildlife watchers report a Holocola thalassinana in Blue Mountains National Park on a given day, against under 5% in March and December–January, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Holocola thalassinana sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Blue Mountains National Park, in our data

GBIF citizen-science records
It is estimated from how often the Holocola thalassinana is recorded against all the insects logged in Blue Mountains National Park (16 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.
