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 →

Rare
Under 5% of wildlife watchers report a Golden-Yellow Wave sighting in Vienna on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1178th most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Golden-Yellow Wave in Vienna on a given day, so our monthly data shows no clear season.
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 Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Golden-Yellow Wave sightings: under 5% 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 Vienna (genus Idaea) are Small Dusty Wave (about 10%), Least Carpet (about 10%) and Riband 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 Vienna (6 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.
