Likely
About 40% of wildlife watchers report an Ezo Spring Cicada sighting in Nikko National Park on a given day, based on 24 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 86 insects we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
May
In that month about 70% of wildlife watchers report an Ezo Spring Cicada in Nikko National Park on a given day, against under 5% in April and August–November, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Ezo Spring Cicada sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Nikko National Park, in our data
Nikko National Park is the only park on Wallace's Line with enough records to rate Ezo Spring Cicada sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ezo Spring Cicada is recorded against all the insects logged in Nikko National Park (24 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.
