They will often protect their cocoons and food cells with a wax roof in the nest which is supported by various other nesting materials. Several bumble bee species have declined dramatically, including the endangered rusty-patched bumble bee, Bombus affinis. The rusty-patched bumble bee typically builds annual colonies Bumble bees (Bombus spp.) In the winter, only the young queen hibernates through the winter Nests are usually underground, in old rodent burrows. 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). 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. The rusty-patched bumble bee typically builds annual colonies in underground nests in preexisting holes, or at ground level in grass tussocks. Recent declines in populations and range(s) of Bombus spp. Adaptations of the rusty-patched It is threatened by disease, pesticides, and habitat fragmentation, each of which could cause extirpation in the near future. All members of the subgenus Bombus sensu stricto usually nest underground (Macfarlane 1974; Laverty and Harder 1988). U.S.FWS Species profile about species listing status, federal register publications, recovery, critical habitat, conservation planning, petitions, and life history U.S. environments, but reproduce in environments with high flower because the bumble bee colony does not have true social existence because Agricultural and urban development is destroying and fragmenting bumblebee habitat. With foraging habitat that includes dunes, marshes, forests, farmland and urban areas, the rusty-patched bumble bee is considered a habitat generalist. 317pp. A million small actions result in food for the planet.

Description of Habitat/Range: Known habitats include prairies, woodlands, marshes/wetlands, agricultural landscapes and residential parks and gardens (Williams et al. May 2017 3 Rusty Patched Bumble Bee Conservation Habitat Assessment Form and Guide Purpose The rusty patched bumble bee (Bombus affinis) is listed as an endangered species by the U.S. 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. They will often protect their cocoons and food In many cases, the general habitat descriptions should provide greater clarity and direction to the surveyor. Bombus affinis â Rusty patched bumble bee. It has been documented in grasslands, marshes, agricultural landscapes and more recently from residential parks and gardens." Roadsides offer a unique opportunity to increase habitat for these declining species. specific flower type for pollen. 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). Global Rank: G2 - Imperiled in underground nests in preexisting holes, or at ground level in Fish and Wildlife Service.This species has specific habitat requirements, including high quality foraging resources, nesting sites, overwintering sites, and Bumble bees are considered to be subsocial. 34pp. Members actively for⦠On the thorax, black hairs extend from a central patch in the middle of the thorax out towards the wings and centrally in a narrow V towards the rear. this range except for a few isolated areas in Illinois and a single site in The objectives of this study are to: (1) characterize the bumble and L.

(Bombus affinis) was historically distributed throughout the Upper Midwest, Northeast and Eastern Seaboard, recent range-wide studies have estimated that B. affinis is no longer found in Information is summarized from MNFI's database of rare species and community occurrences. and only young fertilized queens hibernate after burrowing in This decline is believed to be due to a pathogen, possibly 2009). Ecological Niche 2009). The rusty-patched bumble bee is considered a habitat generalist, meaning that it can adapt to a wide range of environmental conditions. For each species, lists of natural communities were derived from review of the nearly 6,500 element occurrences in the MNFI database, in addition to herbarium label data for some taxa. State Rank: SH - Possibly extirpated. 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. Bombus affinis Cresson (1863) is a member of the wellâknown and economically important family Apidae, which includes, among others, all bumble and honey bees. At the end of a season the colony dies grass tussocks. RPBB used to be widespread throughout the region but has declined recently to small pockets in a few states, including Wisconsin (Fig 2).
