A top-bar hive is a single-story frameless beehive in which the comb hangs from removable bars. The bars form a continuous roof over the comb, whereas the frames in most current hives allow space for bees to move up or down between boxes.
The southern plains bumble bee nests underground. [6] In general, bumble bees are opportunistic nesters that do not dig their own underground nests, but take advantage of pre-existing holes and depressions below the surface formed by rodents or other animals or cavities above the surface created by old logs, stumps, old ground-nesting bird ...

The list presented here is a checklist of global bumblebee [1] species (Tribe Bombini) based on the Bombus phylogeny presented by Cameron et al (2007) [2] and grouped by subgenus following the revision of Williams et al (2008). [3]
The bee lives for about two weeks before dying. The fly then pupates and spends the winter inside the bee, fully developed, before it emerges the following year. Bombus pensylvanicus is host to one "cuckoo" bumble bee species, B. variabilis. [7] Hibernating queen bumble bees are parasitized by a nematode worm, Sphaerularia bombi. This parasite ...
Bombus sonorus, commonly known as the Sonoran bumble bee, is a species of bumble bee in the family Apidae.It is found in Mexico and southwestern North America. [1] [2] [3] Although it has often been categorized as a subspecies of Bombus pensylvanicus [4], it is has since been shown to not hybridize with B. pensylvanicus over a broad area of geographic overlap, confirming its status as a ...
Crotch's bumble bee inhabits grassland and scrub areas, requiring a hotter and drier environment than other bumble bee species, and can only tolerate a very narrow range of climatic conditions. [6] Crotch's bumble bee nests underground, often in abandoned rodent dens. [1] It is a nonmigratory species of bumble bee. [6]
