Rare
Under 5% of wildlife watchers report a White-Spotted Owl-Moth sighting in Perth on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 227th 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 20%, if each day is a fresh chance.
February
In that month about 10% of wildlife watchers report a White-Spotted Owl-Moth in Perth on a given day, against under 5% in March to January, the lowest months. That is one of Perth's driest months, with about 15 mm of rain against 130 mm in July.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most White-Spotted Owl-Moth sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Perth, in our data
Perth is the only city on Wallace's Line with enough records to rate White-Spotted Owl-Moth sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the White-Spotted Owl-Moth that you can see in Perth (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Black-And-White Tiger Moth (about 20%), Southern Moon Moth (about 20%) and White Cedar Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-Spotted Owl-Moth is recorded against all the insects logged in Perth (6 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.
