Rare
Under 5% of wildlife watchers report a Heliothela wulfeniana sighting in Bucharest on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 303rd most-seen of the 361 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.
May–July and September
In those months about 10% of wildlife watchers report a Heliothela wulfeniana in Bucharest on a given day, against under 5% in August and October–April, the lowest months.

GBIF citizen-science records
It is estimated from how often the Heliothela wulfeniana is recorded against all the insects logged in Bucharest (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.
