Mining bees (Andrena spp.), also known as miner bees, sand bees, and digger bees, are named for their practice of nesting underground. These bees are found worldwide, except in Oceania and South America, and are native to North America. Mining bees are small to medium sized bees, ranging from six to 16 mm long. Males are slightly smaller than females. They are brown to black with whitish abdominal bands and are moderately hairy. Mining bees nest in exposed, sandy soils with good drainage. Their nests are often built near or under shrubs, and in banks, hills, and road cut-outs.
