stortapetserarbi

Megachile lagopoda, commonly known as the stortapetserarbi or woolly-footed leafcutter bee, is a solitary bee species belonging to the family Megachilidae. This distinctive bee is characterized by its robust build and the dense hair covering on its legs, which gives it its common name. The species constructs nests by cutting circular pieces from leaves to create brood cells, a behavior typical of leafcutter bees.

Megachile lagopoda inhabits specific ecological niches in northern European regions, where it depends on particular plant species for both nesting materials and nectar sources. The species has experienced severe population declines, leading to its classification as Critically Endangered by the IUCN. Primary threats include habitat loss due to agricultural intensification, urbanization, and changes in land management practices that have reduced the availability of suitable nesting sites and food plants.

Climate change may also be affecting the synchronization between the bee's life cycle and the flowering periods of its preferred plant species. The fragmentation of remaining habitats has further isolated populations, potentially reducing genetic diversity and reproductive success. Conservation efforts focus on habitat restoration, protection of remaining suitable areas, and research to better understand the species' specific ecological requirements.

Monitoring programs have been established to track population trends, though current population data remains limited, making conservation planning challenging.

Megachile lagopoda inhabits specialized environments in northern European regions, typically requiring areas with specific plant communities that provide both suitable leaf material for nest construction and nectar sources. The species depends on semi-natural habitats that maintain the particular combination of vegetation and nesting opportunities necessary for its survival.
