Rare
Under 5% of wildlife watchers report a Yellow-Spotted Longicorn Beetle sighting in Osaka on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 246th most-seen of the 352 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.
June and July
In those months about 10% of wildlife watchers report a Yellow-Spotted Longicorn Beetle in Osaka on a given day, against under 5% in August to May, the lowest months. Those are among Osaka's wettest months, with about 200 mm of rain a month against 55 mm in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow-Spotted Longicorn Beetle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 11
Of the 11 cities where we can rate Yellow-Spotted Longicorn Beetle sightings, Osaka ranks 11th at under 5%. The best odds are in Nanjing (China, about 20%), Nagoya (Japan, about 10%) and Naha (Japan, about 10%).
Same family: Cerambycidae
The closest relatives of the Yellow-Spotted Longicorn Beetle that you can see in Osaka (family Cerambycidae, Longhorn Beetles) are Red Necked Longhorn Beetle (about 10%), Citrus Longhorn Beetle (about 10%) and Thin-Winged Longicorn Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-Spotted Longicorn Beetle is recorded against all the insects logged in Osaka (7 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.
