19 Jul Bumblebee mating, hibernation and death; Stage 4 within the lifecycle of the bumblebee colony
The colony disintegrates, the old queen, workers and males die, and new queens hibernate on this page, Stage 4, males and new queens mate.
Stage 1, the queen emerges from hibernation and begins new colony by by herself.
Phase 2, employees (females) are produced and start to forage; the colony develops and grows.
Stage 3, unfertilised eggs (males) are laid and worker larva develop into brand new queens.

Once the adult males emerge they invest a few days in the nest, but do no work, then they leave the nest for g d and forage for on their own. They are able to often be seen sheltering under the relative heads of flowers whenever it rains or when it gets dark. Well, that is what the majority of the publications say, but recently it was found that some North American bumblebee men do aid in the nest by incubating the young, so their adult life is not only drinking, chasing queens, mating and staying out all night long.
Brand New bumblebee queens

New queens emerge about a week or so after the men. This new queens leave the nest to forage on their own, returning to the nest for shelter, but they don't enhance the current nest conditions. Once the brand new queen is able to mate she flies to where the attractant chemical happens to be deposited by the male and waits for a suitable mate. Then two mate. Most queens mate just once however, many types, e.g.
