With luck
About 10% of wildlife watchers report a Green Tortoise Beetle sighting in Taipei on a given day, based on 142 verified sightings from GBIF citizen-science data. It is the 78th most-seen of the 765 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
June and August
In those months about 20% of wildlife watchers report a Green Tortoise Beetle in Taipei on a given day, against about 10% in July and September–May, the lowest months. Those are among Taipei's wettest months, with about 270 mm of rain a month against 90 mm in February.
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.
5th of 20
Of the 20 cities where we can rate Green Tortoise Beetle sightings, Taipei ranks 5th 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 Taipei (family Chrysomelidae, Leaf Beetles) are Sweetpotato Leaf Beetle (about 20%), Morphosphaera chrysomeloides (about 10%) and Furcated Tortoise 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 Taipei (142 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.
