Andrena vaga, commonly known as the mining bee, is a solitary ground-nesting bee found in Europe. It is medium-sized, measuring around 10-12 mm in length, with a dark black body and dense hair covering. These bees are important pollinators, particularly for early spring flowers, and create underground tunnels for nesting. They are known for their distinctive buzzing sound and are often found in gardens, meadows, and woodland areas.
