In 3 days ~10% in a week ~20%
Taleporia tubulosa, the large birch bright, is a small nocturnal moth from the bagworm moth family (Psychidae). It is found locally in Europe, from southern Scotland, through west and central Europe, east up to Russia and the Balkans. In the north it is found in Fennoscandia. In mountainous areas it is found up to heights of 1,800 meters ASL.
The wings of the male are greyish brown and look frayed, with a wingspan of 15 to 19 millimeters. The females do not have wings, as is usual for bagworm moths. The caterpillars feed on lichen from the genus Parmelia, but they may also eat plant remains. They live in a protective casing made of grass or bark that is usually attached to a tree. The females remain in this casing when adult. The males' flight time ranges from May to June. Wikipedia →

Rare
Under 5% of wildlife watchers report a Large Birch-Bright sighting in Berlin on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 949th most-seen of the 1065 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.
November and December
In those months about 10% of wildlife watchers report a Large Birch-Bright in Berlin on a given day, against under 5% in January to October, the lowest months.
Only Berlin, in our data
Berlin is the only city on Wallace's Line with enough records to rate Large Birch-Bright sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Large Birch-Bright is recorded against all the insects logged in Berlin (5 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.
