Rhyparia purpurata
In 3 days ~10% in a week ~20%
Diacrisia purpurata, the purple tiger, is a moth of the subfamily Arctiinae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is found in Europe, Anatolia, Syria, Transcaucasus, Central Asia (mainly in Kazakhstan and Kyrgyzstan), southern Siberia, Mongolia, Amur Region, northern China, Korea and Japan (Honshu).
The length of the forewings is 18–22 mm for males and 22–25 mm for females. The moth flies June to August depending on the location. The larvae feed on Calluna and sometimes other herbaceous plants and deciduous trees. The species of the genus Rhyparia, including this one, were moved to Diacrisia as a result of phylogenetic research published by Rönkä et al. in 2016. Wikipedia →

Rare
Under 5% of wildlife watchers report a Purple Tiger sighting in Vienna on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 698th 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.
April
In that month about 10% of wildlife watchers report a Purple Tiger in Vienna on a given day, against under 5% in May to March, the lowest months.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Purple Tiger 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.
Only Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Purple Tiger sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Purple Tiger that you can see in Vienna (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Nine-Spotted Moth (about 10%), Four-Spotted Moth (about 10%) and Jersey Tiger (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Purple Tiger is recorded against all the insects logged in Vienna (17 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.
