Eublemma purpurina, the beautiful marbled, is a moth of the family Erebidae. The species was first described by Michael Denis and Ignaz Schiffermüller in 1775. It is found from North Africa through the Iberian Peninsula and southern France east to Romania, southern Russia, southern Turkey up to western central Asia. In the north it ranges to Valais, in eastern Austria and Hungary and the Czech Republic.
These moths have been observed to migrate towards recently burned forest areas in Western Bohemia forests in the Czech Republic alongside other moth species. The wingspan is 20–26 millimetres (0.79–1.02 in). Adults are on wing from May to June and from August to September in two generations.
The larvae feed on creeping thistle (Cirsium arvense). Wikipedia →

Rare
Under 5% of wildlife watchers report a Beautiful Marbled sighting in Vienna on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 1090th 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 Beautiful Marbled in Vienna on a given day, so our monthly data shows no clear season.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Beautiful Marbled sightings with a recorded time, and about half 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 Beautiful Marbled sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Beautiful Marbled 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.
