Rare
Under 5% of wildlife watchers report a Bean Leafroller sighting in Singapore on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 556th most-seen of the 1045 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 Bean Leafroller in Singapore on a given day, so our monthly data shows no clear season.
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.
3rd of 4
Of the 4 cities where we can rate Bean Leafroller sightings, Singapore ranks 3rd at under 5%. The best odds are in Kochi (India, about 10%) and Brisbane (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Bean Leafroller is recorded against all the insects logged in Singapore (19 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.
