Rare
Under 5% of wildlife watchers report a Nacoleia rhoeoalis sighting in Perth on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 154th most-seen of the 275 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January to March
In those months about 10% of wildlife watchers report a Nacoleia rhoeoalis in Perth on a given day, against under 5% in April to December, the lowest months. Those are among Perth's driest months, with about 20 mm of rain a month against 130 mm in July.

Across all the parks we cover, that three-hour window holds the most Nacoleia rhoeoalis sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
3rd of 4
Of the 4 cities where we can rate Nacoleia rhoeoalis sightings, Perth ranks 3rd at under 5%. The best odds are in Melbourne (Australia, about 10%) and Brisbane (Australia, about 10%).

The closest relatives of the Nacoleia rhoeoalis that you can see in Perth (family Crambidae, Crambid Snout Moths) are Hawaiian Beet Webworm Moth (about 10%), Cabbage Centre Grub (about 10%) and Grass Webworm Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Nacoleia rhoeoalis is recorded against all the insects logged in Perth (13 verified sightings), 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.
