In 3 days ~20% in a week ~50%
Megachile parietina is a species of bee in the family Megachilidae. It was described by Geoffroy in 1785. It is native to most of central Europe, as well as parts of eastern Europe. Commonly called the black mud bee, Megachile parietina on the Maltese Islands was described by Thomas Cassar in 2024. Cassar recorded, for the first time, two adult nesting females and four nests in Pembroke, northeast of Malta.
A previous study suggested Megachile parientina could be a suitable pollinator of the orchid Ophrys meitensis, endemic to the Maltese Islands. Wikipedia →

With luck
About 10% of wildlife watchers report a Black Mud Bee sighting in Athens on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 82nd most-seen of the 242 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
March and April
In those months about 20% of wildlife watchers report a Black Mud Bee in Athens on a given day, against under 5% in June to January, the lowest months.
Yes
Of the 3 cities where we can rate Black Mud Bee sightings, Athens has the highest daily chance: about 10%. Next come Prague (Czechia, under 5%) and Vienna (Austria, under 5%).
GBIF citizen-science records
It is estimated from how often the Black Mud Bee is recorded against all the insects logged in Athens (11 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.
