[5] This bumblebee can occupy many kinds of habitat, including meadows, wetlands, agricultural fields, and urban areas, even densely populated cities.

It is a common pollinator in community gardens in New York City and it has been observed near the top of the Empire State Building over 100 stories above ground level.

[1] Bombus griseocollis is found in the southern parts of most Canadian provinces except the Maritimes and most American states excluding the southwest.

[4] This is a eusocial bee, one that forms a colony that works together to rear young with labor divided amongst reproductive and non-reproductive castes.

[7] Specific tasks performed by workers include secreting wax and using it to glue the nest to a substrate, using harvested material to insulate the nest, incubating pupae by wrapping their bodies around the cocoons, regurgitating food for larvae, scraping wax off of discarded pupal cases and recycling it in the construction of honey pots, buzzing when alarmed, inspecting and patrolling the nest, foraging, and feeding.

They scent mark their perches using a glandular secretion containing tetradecyl acetate and butyric acid.

Unlike many bumblebees in North America, it has experienced an average decline of 0%, and in some areas its populations may be increasing.
