Rare
Under 5% of wildlife watchers report a Dwarf Cream Wave sighting in Vienna on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 529th 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.
June
In that month about 10% of wildlife watchers report a Dwarf Cream Wave in Vienna on a given day, against under 5% in July to May, the lowest months. That is one of Vienna's wettest months, with about 90 mm of rain against 40 mm in February.

GBIF citizen-science records
It is estimated from how often the Dwarf Cream Wave is recorded against all the insects logged in Vienna (28 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.
