In 3 days ~10% in a week ~20%
The E. bipunctella invalidly described in 1936 by H. Rebel in L. Osthelder is actually E. distigmatella. Ethmia bipunctella is a diurnal moth from the family Depressariidae. It can be found in Central and Southern Europe, North Africa, Asia and the northeastern part of North America. E. iranella was formerly included here as a subspecies.
The wingspan of the moth ranges from 19–28 millimetres (0.75–1.10 in). The flight time ranges from May to September. The moth is bivoltine, having two generations per year. The most important host plant is the viper's bugloss, but also Anchusa officinalis and plants from the genus Symphytum. Pupae are attached to dead wood. Wikipedia →

Rare
Under 5% of wildlife watchers report a Viper's Bugloss Moth sighting in Vienna on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 895th 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 Viper's Bugloss Moth in Vienna on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Viper's Bugloss Moth is recorded against all the insects logged in Vienna (11 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.
