"The ashy mining bee, classified as solitary, gathers in dense aggregations during spring, transforming a modest patch of turf into a bustling settlement of several hundred bees."
"Males of the ashy mining bee patrol the airspace above the grass, displaying a unique flight rhythm, and engage in competitive mating behavior when females emerge."
"These bees are important pollinators, particularly of oilseed rape, and their foraging activity peaks with the blooming of spring flowers, showcasing their polylectic nature."
"Females navigate back to their nests using environmental cues like grass blades and stones, but occasionally enter the wrong burrow, leading to brief confrontations with other bees."
The ashy mining bee (Andrena cineraria) is a solitary species found in the UK, known for its dense aggregations during spring. Females maintain individual burrows while males patrol the airspace, waiting for females to emerge. Their mating behavior involves multiple males converging on a female. These bees are polylectic, foraging from various spring-flowering plants and are significant pollinators of oilseed rape. Females navigate to their nests using environmental markers, although they sometimes enter the wrong burrow, leading to brief tussles with other bees.
