description Andrena dorsata Overview
Andrena dorsata, commonly called the short-fringed mining bee, is a solitary bee in the family Andrenidae. It occurs across parts of the Palearctic region and is bivoltine, with two adult generations appearing during the year. Females excavate nests in the ground, while adults visit flowers for pollen and nectar; the species is therefore encountered in open, flower-rich habitats rather than living in social colonies like honey bees.
