In 3 days ~10% in a week ~30%
Acrothinium gaschkevitchii is a species of leaf beetle in the family Chrysomelidae. It is distributed in East Asia. The species is named after the wife of Russian diplomat Iosif Goshkevich. She had sent Motschulsky a collection of insects from Japan, including specimens of Acrothinium gaschkevitchii, that she had collected in the vicinity of her residence at Hakodate and during her trips between Honshu and Hokkaido.
A. gaschkevitchii has a shiny metallic appearance, and its back is sparsely covered with setae. In the nominate subspecies, A. g. gaschkevitchii, the pronotum is green in color, and the elytra are golden red to copper-color with green at their margins. Wikipedia →

Rare
Under 5% of wildlife watchers report an Acrothinium gaschkevitchii sighting in Osaka on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 271st 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.
April and May
In those months about 10% of wildlife watchers report an Acrothinium gaschkevitchii in Osaka on a given day, against under 5% in June to March, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Acrothinium gaschkevitchii sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 cities where we can rate Acrothinium gaschkevitchii sightings, Osaka ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Tokyo (Japan, under 5%).

GBIF citizen-science records
It is estimated from how often the Acrothinium gaschkevitchii is recorded against all the insects logged in Osaka (6 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.
