Queen bee lifespan8/11/2023 ![]() Occasionally, they’ll disappear underground for several minutes only to resurface having decided the caverns below were unsuitable for their nest. Look for them flying low over the ground, stopping occasionally to explore cavities and borrows. When the first bumble bees emerge in the late spring, you can observe nest searching behavior of new queens. Occasionally, we find nests near woodland edges where there also tends to be a lot of fallen timber and rodent borrows. Truthfully, we still do not know much about the nesting habits of many bumble bee species, including the criteria they use to select their nests, where they tend to be located, and the success rate of founding queens. A typical slumber ranges from 6-9 months.īumble bees are known as “cavity” nesting bees – a sort of catch all category for nesting habits that encompasses areas like tussocky grass, cavities in rock/talus, and even rodent borrows. Gynes then enter diapause by synthesizing alcohol molecules (similar to antifreeze) to protect their cells and organs from freezing. ![]() Mated gynes will build fat reserves and locate a suitable location for overwintering – usually digging into loose soils and thatch. The switch point to making reproductives (drones and gynes) ranges in time depending on the species, occurring as early as late June, and as late as August-September. ![]() Worker production at this point has typically ceased, and the workers and founding queen will all die out naturally, leaving only the newly mated gynes. Drones and gynes leave the nest and mate. At this point, the queen begins to lay unfertilized eggs, which will develop into males, called drones, and workers will begin to rear fertilized eggs into new queens, called gynes. Late Summer and/or FallĬolonies are typically at their maximal size, ranging from 30 to upwards of 400 individuals (depending on the species). The nest is incubated, with temperatures hovering consistently around 30C even when the outside temperature is far colder, even down to 0C. From hereon out, the queen will remain inside the colony laying eggs and caring for brood. The first workers emerge from their silken cocoons 2-3 weeks after being laid as eggs, and take over the duties of searching for food, caring for brood, and defending the nest. The eggs hatch into larvae, resembling maggots, and progress through several larval stages before spinning a cocoon and completing the transformation, called metamorphosis, into adult workers. The queen will rear the first round of female worker bees alone – having to forage for food, incubate the brood clump, defend the nest, and feed herself. Finally, she lays her first crop of eggs into the pollen balls she has brought back, creating a “brood clump”. She first creates wax pots from glands on her abdomen – in which she stores nectar. Queens now are essentially solitary – founding a nest and provisioning it with pollen and nectar.
