In the winter, only the young queen hibernates through the winter of the bumble bee included these states: Minnesota, Wisconsin, Indiana, to achieve pollination. Nesting habitat. The species occurred broadly across the eastern United States, upper Midwest, and southern Quebec and Ontario. At the end of a season the colony dies The rusty-patched bumblebee (Bombus affinis) appears just like its name describes—a bumblebee with a rust-colored patch on the second abdominal segment of the workers and drones. In most cases, at least one specimen record exists for each listed natural community. They will often protect their cocoons and food cells with a wax roof in the nest which is supported by various other nesting materials. Additionally, planting hedgerows and restoring native grasses along field margins, and in urban parks and residential yards provides habitat for small mammals, whose abandoned holes will in turn become bumblebee nesting and hibernating habitat (Goulson 2010). grass tussocks. The coloration of Bombus affinis queens and males differ from the workers in their lack of a strong rusty patch on the second abdominal segment. These losses are primarily attributed to three main threats: the widespread use of neonicotinoids, a pesticide group highly toxic to bees, on cropland since the early 1990s; both nesting and foraging habitat loss due to increased urbanization and intensified agricultural landscapes, particularly the conversion of pasture to corn and soybeans; and the spread of pathogens from bumblebees used as pollinators in commercial greenhouse operations to wild populations nearby (Colla and Packer 2008, COSEWIC 2010, Grixti et al. lower Michigan, Ohio, Pennsylvania, New York, Vermont, New Hampshire, Maine, But the land has changed, and with it a way of life for this little critter. environments, but reproduce in environments with high flower Since about 2007, however, the species’ distribution has declined across its range in the U.S. (Fig. Last month the rusty patched bumble bee (Bombus affinis) was added to the endangered species list by the U.S. in underground nests in preexisting holes, or at ground level in Commitee on the Status of Endangered Wildlife in Canada. With foraging habitat that includes dunes, marshes, forests, farmland and urban areas, the rusty-patched bumble bee is considered a habitat generalist. Bombus affinis Cresson (1863) is a member of the well-known and economically important family Apidae, which includes, among others, all bumble and honey bees. The rusty-patched bumble bee (Bombus affinis) was once commonly found across the northern part of eastern North America, extending south along the Appalachian mountains. Recovery Strategy for the Rusty-patched Bumble Bee (Bombus affinis) in Canada (2020-02-21) This bumble bee use to roam the vast grasslands of the Midwest, sipping on endless nectar supplies of prairie wildflowers.

Recovery Strategies. 34pp. Evans, E., R. Thorp, S. Jepsen and S.H. Their colonies are considered large compared to those of other bumble bee species; a healthy Rusty Patched Bumble Bee colony may contain as many as 1,000 individual workers. Survey Period: From third week of April to fourth week of October, About the Natural Community Classification, Colla, S.R. Fish and Wildlife Service. It forages from dozens of food plants, including milkweed, sunflowers, clovers and fruit blossoms. It has been documented in grasslands, marshes, agricultural landscapes and more recently from residential parks and gardens." Common and widespread in its distribution prior to the mid-1990s, this species, along with several other North American bumblebees of the same subgenus, has recently experienced dramatic declines throughout its range (COSEWIC 2010). Fish and Wildlife Service.This species has specific habitat requirements, including high quality foraging resources, nesting sites, overwintering sites, and Habitat. State Rank: SH - Possibly extirpated. 34pp. 2008.

Roadsides offer a unique opportunity to increase habitat for these declining species. It is threatened by disease, pesticides, and habitat fragmentation, each of which could cause extirpation in the near future. Roadsides offer a unique opportunity to increase habitat for these declining species. Agricultural and urban development is destroying and fragmenting bumblebee habitat. Abdominal coloration varies. Bombus affinis queens and workers differ slightly in coloration (an uncommon feature in bumble bees), the primary differences being the absence of the black band and narrow V on the thorax, and the absence of the rusty patch in the in the queen. In many cases, the general habitat descriptions should provide greater clarity and direction to the surveyor. they are not social year round.

COSEWIC. this range except for a few isolated areas in Illinois and a single site in Two formerly widespread species have recently declined in Ohio: the Rusty-Patched Bumble Bee (Bombus affinis), designated as federally endangered in 2017, and the Yellow-Banded Bumble Bee (Bombus terricola). Commitee on the Status of Endangered Wildlife in Canada. The Rusty-patched Bumble Bee generally nests one to four feet (30 to 120 cm) below ground in abandoned rodent nests or other cavities (Jepsen et al. Most Bombus queens overwinter in rotten wood or underground (COSEWIC 2010). Entomologists do not have a strong accounting of bumble bee populations and habitats, in part because of the challenges in counting these and other pollinators. RPBB used to be widespread throughout the region but has declined recently to small pockets in a few states, including Wisconsin (Fig 2). Goulson, D. 2010. bumblebees: behavior, ecology and conservation. Habitat: Rusty patched bumble bees once occupied grasslands and tallgrass prairies of the Upper Midwest and Northeast, but most grasslands and prairies have been lost, degraded, or fragmented by conversion to other uses. Its historical range in North America has been throughout the east and upper Midwest of the United States, north to Ontario, Canada, where it is considered a species at risk, east to Q 2013). B. affinis requires three different types of habitats (each for foraging, nesting, and hibernating) which are geographically close to one another, making this species particularly vulnerable to extinction. What is the habitat of rusty patched bumble bee? Surveys typically involve capturing foraging bumblebees with an aerial net and identifying the individual species (Colla and Packer 2008, Grixti et al. Bombus affinis. Worker on wild bergamot (Monarda fistulosa) — Jay Watson. When pollinators move pollen between plants as they gather food for themselves, they provide food for us and countless other creatures. specific flower type for pollen. All members of the subgenus Bombus sensu stricto usually nest underground (Macfarlane 1974; Laverty and Harder 1988). B. affinis and B. terricola are both in the subgenus Bombus, and may be declining because of pathogen spillover (Berenbaum et al. However, some plants do rely on bumble bees Conservation strategies for bumblebees center around preserving healthy natural habitat areas, reducing pesticide/herbicide use, and promoting native wildflower reestablishment within urban and agricultural landscapes. unprotected and vulnerable to attack by many predators. The vital connections that pollinators make are often taken for granted. honey.
