Megachile parietina
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 Prague on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 647th most-seen of the 724 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.
May
In that month about 10% of wildlife watchers report a Black Mud Bee in Prague on a given day, against under 5% in June to April, the lowest months.
2nd of 3
Of the 3 cities where we can rate Black Mud Bee sightings, Prague ranks 2nd at under 5%. The best odds are in Athens (Greece, about 10%).
Same family: Megachilidae
The closest relatives of the Black Mud Bee that you can see in Prague (family Megachilidae, Mason, Leafcutter, Carder, and Resin Bees) are European Orchard Bee (about 10%) and Red Mason Bee (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black Mud Bee is recorded against all the insects logged in Prague (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.
