About 20% of wildlife watchers report a Somadasys brevivenis sighting in Nikko National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 53rd most-seen of the 86 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Somadasys brevivenis is recorded against all the insects logged in Nikko National Park (5 verified sightings from 2019 to 2026), 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.
