Rare
Under 5% of wildlife watchers report a Willow Leaf Beetle sighting in Beijing on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 171st most-seen of the 401 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.
April–June and August
In those months about 10% of wildlife watchers report a Willow Leaf Beetle in Beijing on a given day, against under 5% in July and September–March, the lowest months. Those are among Beijing's wettest months, with about 65 mm of rain a month against almost none in January.
6th of 21
Of the 21 cities where we can rate Willow Leaf Beetle sightings, Beijing ranks 6th at under 5%. The best odds are in Sendai (Japan, about 10%), Rotterdam [The Hague] (Netherlands, about 10%) and Boston (United States, about 10%).
Same family: Chrysomelidae
The closest relatives of the Willow Leaf Beetle that you can see in Beijing (family Chrysomelidae, Leaf Beetles) are Chrysochus chinensis (about 10%), Oides decempunctata (about 10%) and Small Tortoise Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Willow Leaf Beetle is recorded against all the insects logged in Beijing (15 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.
