Boudinotiana puella, the pale orange underwing, is a moth of the family Geometridae. The species was first described by Eugen Johann Christoph Esper in 1787. It is found in isolated populations in central Europe, ranging to southern Russia in the east.
The wingspan is 29–34 mm for males and 27–30 mm for females. Adults are on wing from February to April in one generation per year. The larvae feed on the leaves of Populus species, especially Populus tremula. The larvae can be found from May to June. The species overwinters in the pupal stage. Wikipedia →

Rare
Under 5% of wildlife watchers report a Boudinotiana puella sighting in Vienna on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 559th 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.
February and March
In those months about 10% of wildlife watchers report a Boudinotiana puella in Vienna on a given day, against under 5% in April to January, the lowest months.
Only Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Boudinotiana puella sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Boudinotiana puella is recorded against all the insects logged in Vienna (25 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.
