Only Fertő-Hanság National Park, in our data
Fertő-Hanság National Park is the only park on Wallace's Line with enough records to rate Ochraceous Wave sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ochraceous Wave is recorded against all the insects logged in Fertő-Hanság National Park (6 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.
