Rare
Under 5% of wildlife watchers report an Acrosternum heegeri sighting in Milan on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 315th most-seen of the 351 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.
October and November
In those months about 10% of wildlife watchers report an Acrosternum heegeri in Milan on a given day, against under 5% in December to September, the lowest months. Those are among Milan's wettest months, with about 120 mm of rain a month against 45 mm in January.

GBIF citizen-science records
It is estimated from how often the Acrosternum heegeri is recorded against all the insects logged in Milan (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.
