Rare
Under 5% of wildlife watchers report a Heliomystis electrica sighting in Blue Mountains National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 681st most-seen of the 789 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
March–May and October
In those months about 10% of wildlife watchers report a Heliomystis electrica in Blue Mountains National Park on a given day, against under 5% in June–September and November–February, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Heliomystis electrica sightings with a recorded time, and about 6 in 10 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 Heliomystis electrica sightings, Blue Mountains National Park ranks 2nd at under 5%. The best odds are in Great Otway National Park (Australia, about 10%).
Same family: Geometridae
The closest relatives of the Heliomystis electrica that you can see in Blue Mountains National Park (family Geometridae, Geometer Moths) are Apple Looper (about 20%), Black Geometrid (about 10%) and Plantain Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Heliomystis electrica is recorded against all the insects logged in Blue Mountains National Park (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.
