Rare
Under 5% of wildlife watchers report a Bean Leafroller sighting in Bangkok on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 228th most-seen of the 245 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.
November
In that month about 10% of wildlife watchers report a Bean Leafroller in Bangkok on a given day, against under 5% in December to October, the lowest months. That is one of Bangkok's driest months, with about 40 mm of rain against 280 mm in September.
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.
4th of 4
Of the 4 cities where we can rate Bean Leafroller sightings, Bangkok ranks 4th at under 5%. The best odds are in Kochi (India, about 10%), Brisbane (Australia, about 10%) and Singapore (Singapore, under 5%).
GBIF citizen-science records
It is estimated from how often the Bean Leafroller is recorded against all the insects logged in Bangkok (5 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.
