Possible
About 20% of wildlife watchers report an Apple Looper sighting in Perth on a given day, based on 270 verified sightings from GBIF citizen-science data. It is the 8th most-seen of the 275 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
October to December
In those months about 30% of wildlife watchers report an Apple Looper in Perth on a given day, against under 5% in May to July, the lowest months. Those are among Perth's driest months, with about 25 mm of rain a month against 130 mm in July.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Apple Looper 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.
Yes
Of the 5 cities where we can rate Apple Looper sightings, Perth has the highest daily chance: about 20%. Next come Auckland (New Zealand, about 20%) and Melbourne (Australia, about 20%).
Same family: Geometridae
The closest relatives of the Apple Looper that you can see in Perth (family Geometridae, Geometer Moths) are Red-Lined Looper (about 20%), Insigillated Pug (about 10%) and Pink-Bellied Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Apple Looper is recorded against all the insects logged in Perth (270 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.
