This species is a cleptoparasite of several Megachile species (Megachile inermis; M. relativa; M. rotundata; M. frigida; M. latimanus) and thus limited by the range and abundance of its host. Northwest Territories is a large jurisdiction. The bee fauna in this territory is poorly studied in most areas. The ecozones within the jurisdiction remain largely unmodified, aside from the longer-term effects of climate change. There is little data for this species in Canada, and the species is known in NT only from Yellowknife. Northwest Territories is a large jurisdiction with a land area of approximately 1,346,106 km2. The territory includes five ecozones (Arctic, Boreal Plains, Taiga Cordillera, Taiga Plains and Taiga Shield). The largest ecozones represented in this territory are the Taiga Plains and Taiga Shield. Threats to bees and bee communities in this territory are unknown although are likely minimal. The bee fauna in this territory is poorly studied in most areas , mainly due to inaccessibility, excluding urban areas and transport corridors connecting these urban areas. The ecozones within the jurisdiction remain largely unmodified, aside from the longer-term effects of climate change. Given the natural history information available, we assume that the bee fauna is largely unchanged, albeit only suitable in habitats with floral resources and nesting sites. In Canada known from NT (Yellowknife), BC (Western Interior Basin), AB, and southern ON. Cleptoparasite of Megachile relativa. Actual distribution of the bee may be more widespread based on the distribution of its bee host. Cumulative threats, mainly within areas of human habituation, include habitat loss and/or conversion to agriculture/urban development, invasive non-native species, climate change, livestock grazing, recreational use, etc. (as outlined in short and long-term trends) and have all likely contributed to declines in bee abundance. The specific impact to each bee species is unknown due to lack of specimen data, surveys, natural history information of a species and analysis of these impacts on these variables. These threats may not applicable to portions of ecozones with large natural areas. Species specific threats are unstudied for most bees. (HSS010)
