Oraesia excavata
In 3 days ~10% in a week ~20%
Oraesia excavata is a species of moth of the family Erebidae first described by Arthur Gardiner Butler in 1878. It is found in Japan, Korea, China, Thailand and Taiwan and has recently been recorded from Hawaii. Adults are orange and mimic a dead leaf. They pierce fruit (including prune, citrus, grape, peach, pear, apple, guava, papaya, mango, banana and loquat) to suck the juice.
The larvae feed on Menispermaceae species, possibly including Cocculus orbiculatus, Lepisanthes rubiginosa and Stephania japonica. Wikipedia →

Rare
Under 5% of wildlife watchers report a Fruit-Piercing Moth sighting in Osaka on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 304th 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 20%, if each day is a fresh chance.
February and August–October
In those months about 10% of wildlife watchers report a Fruit-Piercing Moth in Osaka on a given day, against under 5% in March–July and November–January, the lowest months.
Among the best
Of the 2 cities where we can rate Fruit-Piercing Moth 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 Fruit-Piercing Moth is recorded against all the insects logged in Osaka (5 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.
