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 Tokyo on a given day, based on 45 verified sightings from GBIF citizen-science data. It is the 263rd 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 30%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report an Acrothinium gaschkevitchii in Tokyo on a given day, against under 5% in July to April, 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.
Yes
Of the 3 cities where we can rate Acrothinium gaschkevitchii sightings, Tokyo has the highest daily chance: under 5%. Next come Osaka (Japan, under 5%) and Taipei (Taiwan, under 5%).
Same family: Chrysomelidae
The closest relatives of the Acrothinium gaschkevitchii that you can see in Tokyo (family Chrysomelidae, Leaf Beetles) are Aulacophora nigripennis (about 20%), Lema diversipes (about 20%) and Nepalese Turtle Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Acrothinium gaschkevitchii is recorded against all the insects logged in Tokyo (45 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.
