Abdominal coloration varies. COSEWIC assessment and status report on the Rusty-patched Bumble Bee Bombus affinis in Canada. Agricultural and urban development is destroying and fragmenting bumblebee habitat. This decline is believed to be due to a pathogen, possibly Habitat. the soil. Data may not reflect true distribution since much of the state has not been thoroughly surveyed. The species occurred broadly across the eastern United States, upper Midwest, and southern Quebec and Ontario. Roadsides offer a unique opportunity to increase habitat for these declining species. 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. At the end of a season the colony dies Wong, S.A. Cameron and C. Favret. specific flower type for pollen.

It In most cases, at least one specimen record exists for each listed natural community. Global Rank: G2 - Imperiled are important pollinators of many plants around the world. Bombus affinis. 2014). 2008. 2009. But the land has changed, and with it a way of life for this little critter. are attributed to habitat loss, pesticide use and invasive pathogens. rusty-patched bumble bee is mostly found in cool or temperate regions. 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).

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. Bombus affinis) occurs in the Eastern and Midwestern United States and southern Canada. The bee — officially Bombus affinis — is called the rusty patched bumblebee because of the small rust-colored patch, surrounded by yellow, ... habitat loss and pesticides. other nesting materials. as it appears in: ranges across Quebec to the Dakotas and south to Georgia. In future versions of the Rare Species Explorer, we hope to incorporate natural community fidelity ranks for each taxon. Bombus affinis, commonly known as the rusty patched bumble bee, is a species of bumblebee endemic to North America. It is threatened by disease, pesticides, and habitat fragmentation, each of which could cause extirpation in the near future. to achieve pollination. However, some plants do rely on bumble bees Rarely, there will be reddish pile on other abdominal segments (3-6). COSEWIC assessment and status report on the Rusty-patched Bumble Bee Bombus affinis in Canada. This is Bumble bees are considered to be subsocial. plants and crops. Decline of bumble bees (Bombus) in the North American Midwest. this range except for a few isolated areas in Illinois and a single site in State Rank: SH - Possibly extirpated. Rusty-patched Bumble Bee (Bombus affinis) in Canada [Proposed], Species at Risk Act Recovery Strategy Series, Environment and Climate Change Canada, Ottawa, vii + 56 p. For copies of the recovery strategy, or for additional information on species at risk, The Rusty Patched Bumble Bee is a highly social species that lives in colonies consisting of a single queen, female workers, and males. For certain taxa, especially poorly collected or extirpated species of prairie and savanna habitats, natural community lists were derived from inferences from collection sites and habitat preferences in immediately adjacent states (particularly Indiana and Illinois). They are generalist foragers, and do not depend on a They will often protect their cocoons and food cells with a wax roof in the nest which is supported by various other nesting materials. Bombus affinis — Rusty patched bumble bee. Black. cells with a wax roof in the nest which is supported by various environments, but reproduce in environments with high flower 2013). Ecological Niche 34pp. They do not seem to associate with specific Surveys typically involve capturing foraging bumblebees with an aerial net and identifying the individual species (Colla and Packer 2008, Grixti et al. Adaptations of the rusty-patched 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. All members of the subgenus Bombus sensu stricto usually nest underground (Macfarlane 1974; Laverty and Harder 1988). Nests are usually underground, in old rodent burrows. 2010. One of few areas in which Bombus affinis still survives in depleted numbers is the metropolitan area of St. Paul and Minneapolis. Queens are larger (about .8 inches), with the thorax and first two abdominal segments being yellow, while the remainder of the abdomen is dark black. Survey Period: From third week of April to fourth week of October, About the Natural Community Classification, Colla, S.R. 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. Maryland, Virginia, North Carolina, South Carolina, Georgia, and portions of Biodiversity and Conservation 17: 1379-91. 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. US Status: LE - Listed Endangered U.S.FWS Species profile about species listing status, federal register publications, recovery, critical habitat, conservation planning, petitions, and life history U.S. Fish & Wildlife Service ECOS Environmental Conservation Online System It has been documented in grasslands, marshes, agricultural landscapes and more recently from residential parks and gardens."
