Rare
Under 5% of wildlife watchers report a Black Pennant sighting in Bucharest on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 256th 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.
June and July
In those months about 10% of wildlife watchers report a Black Pennant in Bucharest on a given day, against under 5% in August to May, the lowest months. Those are among Bucharest's wettest months, with about 75 mm of rain a month against 35 mm in February.
2nd of 2
Of the 2 cities where we can rate Black Pennant sightings, Bucharest ranks 2nd at under 5%. The best odds are in Kuwait City (Kuwait, about 10%).
Same family: Libellulidae

GBIF citizen-science records
It is estimated from how often the Black Pennant is recorded against all the insects logged in Bucharest (6 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.
