, one of the rarest bees in North America, is a cleptoparasite of bees which themselves are uncommon oligoleges of oil-producing flowers. Only two specimens of the cleptoparasite have been reported from Canada since the 1960s, both from Nova Scotia.
A recently collected specimen of from Alberta, Canada confirms this species from that province and greatly increases its known range in western North America.
