For most bumblebees species, winter is a time for hibernation. Basically, in the fall new bumblebee queens who had hatched earlier in the summer & mated in late summer/early fall, burrow into nests in the ground and hibernate for the winter. As winter approaches in the bumblebees can be seen foraging for food to ensure that the queens are well fed. Do you know?

They are less active but not necessarily dormant. A single bumblebee can do 50 times the work of a honeybee and carries a bigger payload of pollen. If asked to name a key pollinator in the United States, youre likely to think first of the honey bee.

Just like all the other creatures on the planet, bees have a unique way of coping with low temperature. The hair on their bodies prevents heat from escaping. The bee is cold blooded, so the hive must maintain a warm temperature to keep the colony alive. Bumble bee nests are small compared to honey bees, as each nest contains only a few hundred individuals. They burrow into soft earth or under logs and stones to escape the frost, … So if you find any bumblebees, it’s fine to give them shelter from very harsh weather overnight, but they will need to be outside again as soon as possible. As ambient temperatures rise, the bees on the outside of the group separate a bit, to allow more air flow. Where do other insects go in winter? Through winter and early spring depending on the outside temperature the new queens will hibernate in the ground resting, quietly waiting for the spring to bring on warmer temperatures and flowers loaded with pollen and nectar. They eat and work all winter long—activity which requires a large cache of stored food. The older worker bees create the outside layer of the cluster while the younger bees are tucked in the middle.

Honeybees spend the winter in the hive and protect the queen by forming a cluster to keep her warm. The bees create a shivering movement by vibrating their wing muscles to generate heat. As temperatures get colder, she produces a chemical in her body (glycerol) that keeps her from freezing, and she remains buried all winter. Most of them have the same social structure as honey bees do, there is a queen , and there are workers and drones . That’s what I found out from my friends Rachel Olsson and Elias Bloom. The cycle of a bumblebee colony is usually at an end now, the workers have busily foraged to enable a new generation to be produced with the focus of the colony being switched to producing queen and worker bees. It should then lap this up, and will use the energy to heat its body up and fly off. But for the Buff-tailed bumblebee (Bombus terrestris), winter can be just as busy a time as the rest of the year.

She hibernates during the winter months underground and starts a new colony in the spring. Likewise, solitary bees also only live for about a year before dying off. The outer bees remain motionless, acting as an insulation layer. Solitary bees cannot form clusters to protect the queen for the coming generation, they, therefore, ensure their own survival. After placement of the hive, let the bumblebees settle down for a while (½ - 1 hour) before opening the flight hole. Colonies can contain between 50 and 500 individuals, according to the National Wildlife Federation. The common species are 3/4 inch in length or more. Pollinators, the small creatures responsible for one out of every three bites of food we eat, employ several strategies to survive winter. After the new queens are produced and mate in the summer and autumn, the workers, males and old queens die off by winter time.
