Rare
Under 5% of wildlife watchers report a Long-Tailed Bombyx sighting in Brisbane on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 806th most-seen of the 1083 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Long-Tailed Bombyx in Brisbane on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Long-Tailed Bombyx 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.
4th of 4
Of the 4 cities where we can rate Long-Tailed Bombyx sightings, Brisbane ranks 4th at under 5%. The best odds are in Perth (Australia, about 10%), Melbourne (Australia, about 10%) and Sydney (Australia, under 5%).
Same family: Notodontidae

GBIF citizen-science records
It is estimated from how often the Long-Tailed Bombyx is recorded against all the insects logged in Brisbane (8 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.
