The two-spotted bumble bee, Cresson, 1863 (Hymenoptera, Apidae), is a common species in central North America, with few published records of this species in Canada west of Ontario or east of Quebec.
Based on recently collected specimens from Saskatchewan and confirmed records posted to iNaturalist (https://www.inaturalist.org/) in the past 10 years (i.e. since 2013), we provide evidence that this species has only recently expanded its range in Canada, westwards into the Prairies Ecozone (Manitoba, Saskatchewan) and east into the Maritime Provinces (New Brunswick, Nova Scotia, Prince Edward Island).
双斑熊蜂,克雷森,1863年(膜翅目,蜜蜂科),是北美中部的常见物种,在安大略省以西或魁北克省以东的加拿大地区,关于该物种的已发表记录很少。
基于最近从萨斯喀彻温省采集的标本以及过去10年(即自2013年以来)发布到iNaturalist(https://www.inaturalist.org/)上的确认记录,我们提供证据表明,该物种最近才在加拿大扩大其分布范围,向西进入草原生态区(曼尼托巴省、萨斯喀彻温省),向东进入海洋省份(新不伦瑞克省、新斯科舍省、爱德华王子岛)。
