Rare black bees, Xylocopa valga, observed on Wrocław University campus, highlight climate impacts and ecological adaptability of this protected species.
Discovery of a Protected Species
Researchers at Wrocław University observed the rare Xylocopa valga, or violet carpenter bee, on campus. This heat-loving species, uncommon in Poland, was spotted by student Grzegorz Lewek near a broken linden tree. Known for nesting in dead wood, the bee is strictly protected and listed in the Polish Red Data Book of Animals.
Adaptation and Climate Impacts
The appearance of Xylocopa valga in Lower Silesia may be linked to climate change or its ecological flexibility. The species adapts to both natural habitats, such as forest edges, and man-made environments like parks and gardens.
Key Pollinator with Versatile Habitats
These bees pollinate over 30 plant species, including sage, blackthorn, and wild cherry. They often winter in decayed tree trunks or cracks in walls, occasionally utilizing wooden structures. The sighting at Wrocław University underscores the growing importance of understanding species migration amid environmental changes.
