Rare
Under 5% of wildlife watchers report an Opigena polygona sighting in Vienna on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 1028th 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.
September and October
In those months about 10% of wildlife watchers report an Opigena polygona in Vienna on a given day, against under 5% in November to August, the lowest months.
Only Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Opigena polygona sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae
The closest relatives of the Opigena polygona that you can see in Vienna (family Noctuidae, Cutworm Moths and Allies) are Silver Υ (about 20%), Large Yellow Underwing (about 10%) and Cotton Bollworm Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Opigena polygona is recorded against all the insects logged in Vienna (8 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.
