Rare
Under 5% of wildlife watchers report a Blood Vein sighting in Vienna on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the 362nd 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 30%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report a Blood Vein in Vienna on a given day, against under 5% in October to June, the lowest months.

GBIF citizen-science records
It is estimated from how often the Blood Vein is recorded against all the insects logged in Vienna (41 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.
