Dorcus rectus
In 3 days ~50% in a week ~80%
Dorcus rectus, the little stag beetle, is a species of beetles in the family Lucanidae. It can be found in China(Liaoning), Korea, Japan, Russia. These beetles have a distinctive red shell that separates them from Dorcus curvidens. Males of this species have been observed to have mandible trimorphism, a characteristic that has only been described in two species of Lucanidae—with the other one being Odontolabis cuvera—"and a small number of other invertebrates" as of 2017. The mandibles are used by males as weapons. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Little Stag Beetle is recorded against all the insects logged in Nagoya (24 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.
