Andrena is one of the world’s largest genera of bees. There are probably only a few people in all of North America who possess the specialized knowledge necessary to make a reliable species identification. Andrena bees are remarkably cold tolerant and are some of the first small bee species to frequent flowers in the spring, although this little guy was clearly struggling with the chilly morning air.
