Rare
Under 5% of wildlife watchers report a Green Tortoise Beetle sighting in Bangkok on a given day, based on 6 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.
July
In that month about 10% of wildlife watchers report a Green Tortoise Beetle in Bangkok on a given day, against under 5% in August to June, the lowest months. That is one of Bangkok's wettest months, with about 170 mm of rain against 10 mm in December.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Green Tortoise Beetle sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
20th of 20
Of the 20 cities where we can rate Green Tortoise Beetle sightings, Bangkok ranks 20th at under 5%. The best odds are in Xiuying District (China, about 20%), Thrissur (India, about 20%) and Dhaka (Bangladesh, about 20%).
GBIF citizen-science records
It is estimated from how often the Green Tortoise Beetle is recorded against all the insects logged in Bangkok (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.
