In 3 days ~10% in a week ~20%
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 →

Rare
Under 5% of wildlife watchers report a Black Mud Bee sighting in Vienna on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 1090th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black Mud Bee in Vienna on a given day, so our monthly data shows no clear season.
3rd of 3
Of the 3 cities where we can rate Black Mud Bee sightings, Vienna ranks 3rd at under 5%. The best odds are in Athens (Greece, about 10%) and Prague (Czechia, under 5%).
GBIF citizen-science records
It is estimated from how often the Black Mud Bee is recorded against all the insects logged in Vienna (7 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.
