Rare
Under 5% of wildlife watchers report a Dusky Grass-Veneer sighting in Vienna on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 838th 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.
June
In that month about 10% of wildlife watchers report a Dusky Grass-Veneer in Vienna on a given day, against under 5% in July to May, the lowest months. That is one of Vienna's wettest months, with about 90 mm of rain against 40 mm in February.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Dusky Grass-Veneer sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Dusky Grass-Veneer sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Crambidae
The closest relatives of the Dusky Grass-Veneer 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 Dusky Grass-Veneer is recorded against all the insects logged in Vienna (12 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.
