Interpretive Summary: While bees are essential to productive agriculture and effective pollination of native plants, bees that are not native may pose a threat to native bees by competing for pollen and nectar or by usurping the nests of native bees. One such species is a carder bee from the Old World first found in New Jersey in 2008. Here we record the expansion of this species to include Illinois and Minnesota. Traits that will help in recognizing this species along with high quality pictures of the bee including close-ups of diagnostic traits are included. Potential impacts are discussed

Technical Abstract: We report the first records of Pseudoanthidium nanum (Mocsáry) in Illinois and Minnesota in 2016 and 2018, respectively. This represents a relatively rapid expansion since P. nanum was first detected in New Jersey in 2008. In order to help monitor the spread of this bee, we provide information on how to identify P. nanum and provide images of the general habitus, diagnostic features, and male genitalia. Finally, we confirm the taxonomic identity of P. nanum in the United States and highlight potential impacts on native anthidiines.
