In the United States, bees are primarily raised in mild southern climates, and sold to beekeepers across the country. The bees are raised the year before they are sold, and they are packaged as soon as the weather allows. You can easily replace any bees you lost over the winter, provided you order them in advance.
Italian bees are the most common in North America. This is an advertisement for a standard 3lb package with a marked queen. A marked queen is a queen bee with a colored dot on her back so you can find her more easily.
if you ever feel bad for talking about your interests too much, just remember that vergil not only wrote an entire 600 line poem about the art of beekeeping with loving language about how bees are like little romans, but he also included an extensive bee metaphor in the aeneid, a book which is a patriotic founding story about rome and has nothing at all to do with bees
