With luck
About 10% of wildlife watchers report a Green Tortoise Beetle sighting in Singapore on a given day, based on 76 verified sightings from GBIF citizen-science data. It is the 309th 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 30%, if each day is a fresh chance.
May, July and October–January
In those months about 10% of wildlife watchers report a Green Tortoise Beetle in Singapore on a given day, against under 5% in February–April, June and August–September, the lowest months.
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.
18th of 20
Of the 20 cities where we can rate Green Tortoise Beetle sightings, Singapore ranks 18th at about 10%. The best odds are in Xiuying District (China, about 20%), Thrissur (India, about 20%) and Dhaka (Bangladesh, about 20%).
Same family: Chrysomelidae
The closest relatives of the Green Tortoise Beetle that you can see in Singapore (family Chrysomelidae, Leaf Beetles) are Baliosus pectoralis (about 10%), Gonophora pulchella (about 10%) and Sweetpotato Leaf Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green Tortoise Beetle is recorded against all the insects logged in Singapore (76 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.
