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 ...
A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus Bombus, part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini, though a few extinct related genera (e.g., Calyptapis) are known from fossils.
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]
Historically, Bombus occidentalis, the so-called "western bumble bee" was the most common species, with a distribution all the way from California to British Columbia and Alaska, but diseases introduced by commercial rearing operations in the eastern United States brought coastal populations of B. occidentallis to the brink of extinction, and B ...
A decline in bee population leads to a decline in crop yield, which will then result in a reduction in the food supply and cause economic hardships for farmers. [ 24 ] [ 25 ] Commercially produced B. impatiens is one of the most important species of pollinator bees that are used by greenhouse industry in North America, [ 7 ] including Canada ...
Bombus occidentalis, the western bumble bee, is one of around 30 bumble bee species present in the western United States and western Canada. [1] A recent review of all of its close relatives worldwide appears to have confirmed its status as a separate species.
The American bumble bee population has seen a near 90% decline in recent decades relative to other bee species, mostly affecting the northern edges of their range, according to FWS.
The two-spotted bumble bee (Bombus bimaculatus) is a species of social bumble bee found in the eastern half of the United States and the adjacent south-eastern part of Canada. In older literature this bee is often referred to as Bremus bimaculatus , Bremus being a synonym for Bombus . [ 3 ]
