Evergestis frumentalis is a moth of the family Crambidae. It is found from the Iberian Peninsula through southern and central Europe and southern Fennoscandia to central Asia and southern Siberia. The species was first described by Carl Linnaeus in 1761.
The wingspan is 29–35 mm. There are two generations per year with adults on wing in April and August. The larvae feed on Descourainia sophia, Sisymbrium, Sinapis (including S. arvensis) and Isatis (including I. tinctoria) species. The larvae of the second generation overwinter in a cocoon in the soil. Wikipedia →

Rare
Under 5% of wildlife watchers report an Evergestis frumentalis sighting in Vienna on a given day, based on 37 verified sightings from GBIF citizen-science data. It is the 399th 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 30%, if each day is a fresh chance.
April and May
In those months about 10% of wildlife watchers report an Evergestis frumentalis in Vienna on a given day, against under 5% in June to March, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Evergestis frumentalis sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
3rd of 5
Of the 5 cities where we can rate Evergestis frumentalis sightings, Vienna ranks 3rd at under 5%. The best odds are in Madrid (Spain, about 10%) and Prague (Czechia, about 10%).
Same family: Crambidae
The closest relatives of the Evergestis frumentalis that you can see in Vienna (family Crambidae, Crambid Snout Moths) are Box Tree Moth (about 10%), Straw-Barred Pearl (about 10%) and Rusty Dot Pearl (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Evergestis frumentalis is recorded against all the insects logged in Vienna (37 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.
