With luck
About 10% of wildlife watchers report a Black Geometrid sighting in Blue Mountains National Park on a given day, based on 71 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 38th most-seen of the 789 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Black Geometrid in Blue Mountains National Park on a given day, against under 5% in April and May, the lowest months. That is one of Blue Mountains National Park's driest months, with about 50 mm of rain against 150 mm in March.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Black Geometrid sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
2nd of 2
Of the 2 parks where we can rate Black Geometrid sightings, Blue Mountains National Park ranks 2nd at about 10%. The best odds are in Great Otway National Park (Australia, about 20%).

GBIF citizen-science records
It is estimated from how often the Black Geometrid is recorded against all the insects logged in Blue Mountains National Park (71 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.
