Idaea aureolaria is a species of moth of the family Geometridae. It is found from Spain and France through central Europe to the Balkan Peninsula and east to Siberia. It is also found from Turkey to Central Asia. The wingspan is 16–20 millimetres (0.63–0.79 in) for males and 14–19 millimetres (0.55–0.75 in) for females. Adults are mainly on wing in June and July, but a second generation with adults on wing from August to September might occur.
The larvae are polyphagous and have been recorded feeding on Rumex, Onobrychis, Securigera varia and Vicia dumetorum. The species overwinters in the larval stage. Wikipedia →

With luck
About 10% of wildlife watchers report a Golden-Yellow Wave sighting in Pyrénées National Park on a given day, based on 24 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 403rd most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June and July
In those months about 10% of wildlife watchers report a Golden-Yellow Wave in Pyrénées National Park on a given day, against under 5% in August to May, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Golden-Yellow Wave 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 Pyrénées National Park, in our data
Pyrénées National Park is the only park on Wallace's Line with enough records to rate Golden-Yellow Wave sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Idaea
The closest relatives of the Golden-Yellow Wave that you can see in Pyrénées National Park (genus Idaea) are Riband Wave (about 10%), Small Fan-Footed Wave (about 10%) and Portland Ribbon Wave (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Golden-Yellow Wave is recorded against all the insects logged in Pyrénées 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.
