Possible
About 20% of wildlife watchers report a Bean Leafroller sighting in Daintree National Park on a given day, based on 43 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 47th most-seen of the 856 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.
March–April and June–July
In those months about 30% of wildlife watchers report a Bean Leafroller in Daintree National Park on a given day, against under 5% in January and October–November, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Bean Leafroller 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.
Yes
Of the 3 parks where we can rate Bean Leafroller sightings, Daintree National Park has the highest daily chance: about 20%. Next come Lamington National Park (Australia, about 10%) and Springbrook National Park (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Bean Leafroller is recorded against all the insects logged in Daintree National Park (43 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.
