Journal post 1

Welcome to the South Dakota Bumble Bees project. It is April 8, and days are getting warmer. It is only a matter of time until we start seeing the first bumble bees of the year. Most of the early bumble bees will be queens. Unlike honey bees, where the entire colony overwinters, only queen bumble bees hibernate, all the workers and drones do not live past the fall. Did you know, that for many species of bumble bees, queens look different from the workers?

The queen will find a suitable nesting area (hole in the ground, a bird box, under an outbuilding) and lay her first group of eggs. She will keep her eggs warm by shivering (generating heat through moving muscles). She will have a larder of pollen and nectar she eats while tending her eggs. Once the eggs hatch, she will make foraging trips to feed the larvae. When the larvae mature they become the first group of workers for the year, and the queen will no longer leave the nest. The queen will produce workers for most of the summer, but as summer becomes fall, the queen will produce males (all workers are female) and future queens. Unlike the workers, once a queen leaves the nest, she mates and eats pollen and nectar to put on fat. The fat will nourish her throughout the winter, and the cycle begins once again.

I hope everyone gets outsides. Have fun, and keep looking for the bumble bees!

I just signed up - I am super excited to help in anyway that I can with this project. I have a ton of bumble bees that visit my wild flowers (wild, as in unmanaged - ha!). I already had one yesterday on a crocus. I will upload the photo to the observations page.

To all the great photographers - I do have one request. Please take a photo of the back of the bumble bee AND one that includes the head/face. Some bumble bees (i.e. Hunt's BB) have hair on their face that can identify them from similar bumble bees. Thanks for joining us on this effort!!
