Rare
Under 5% of wildlife watchers report an Apriona rugicollis sighting in Tokyo on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 406th most-seen of the 1013 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 and August
In those months about 10% of wildlife watchers report an Apriona rugicollis in Tokyo on a given day, against under 5% in September to June, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Apriona rugicollis sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
9th of 10
Of the 10 cities where we can rate Apriona rugicollis sightings, Tokyo ranks 9th at under 5%. The best odds are in Hangzhou (China, about 10%), Taichung (Taiwan, about 10%) and Taipei (Taiwan, about 10%).
Same family: Cerambycidae
The closest relatives of the Apriona rugicollis that you can see in Tokyo (family Cerambycidae, Longhorn Beetles) are Citrus Longhorn Beetle (about 10%), Paraglenea fortunei (about 10%) and Aeolesthes chrysothrix (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Apriona rugicollis is recorded against all the insects logged in Tokyo (23 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.
