Pseudoanthidium nanum (Mocsáry, 1880[“1881”])

European Small-Woolcarder

Notes: The presence of this European bee in Connecticut has been documented in three counties by six photo observations on iNaturalist, all urban locations (https://www.inaturalist.org/observations?place_id=49&taxon_ id=499394). This exotic species (see Figure 2 , A) has also been recently detected for the first time in Rhode Island on iNaturalist in 2021 (https://www.inaturalist.org/observations/91111117). Pseudoanthidium nanum is easily identified from photos in its exotic range, as its black tegula differentiates it from other visually similar Anthidiini in the Northeastern United States, especially Anthidium oblongatum . Thus, digital community science portals are a valuable tool for tracking how this species is spreading in the region.
