This species is large in comparison to other bumblebees and is unusual among bumblebees because the hairs of the abdomen appear flattened rather than fluffy like most other bumblebees. Queens range in size from 0.97 to 1.07 inches (25-27 mm) while workers range in size from 0.56 to 0.75 inches (15-19 mm). [ 6 ]
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]
In older literature this bee is often referred to as Bremus bimaculatus, Bremus being a synonym for Bombus. [3] The bee's common name comes from the two yellow spots on its abdomen. [4] Unlike many of the other species of bee in the genus Bombus, B. bimaculatus is not on the decline, but instead is very stable. They are abundant pollinators ...

All insects have three main body parts; the head, thorax, and abdomen. [3] Bumble bee species identification tends to refer to colorations on the abdominal segments. The abdominal segments are numbered from T1 to T6 (T7 if male) starting from the abdominal segment closest to the thorax and then working ventrally.
They must have body temperatures of at least 29-30 degrees Celsius before they are able to free fly independently in the air. [13] Like honeybees , they produce heat before their flight. To raise their body temperature, specifically their thoracic temperature, these bees must expend a lot of energy.
Apidae is the largest family within the superfamily Apoidea, containing at least 5700 species of bees.The family includes some of the most commonly seen bees, including bumblebees and honey bees, but also includes stingless bees (also used for honey production), carpenter bees, orchid bees, cuckoo bees, and a number of other less widely known groups.
Common plants visited by the workers in a sample included ceanothus, thistles, sweet peas, lupines, rhododendrons, Rubus, willows, and clovers. Queens emerge from hibernation in late January, the first workers appear in early March, and the males follow by the end of April.
