The geometrid moth Hemithea aestivaria (Hübner, 1789) was introduced from Europe to North America, first detected in British Columbia in 1973. Until 2019, its North American range was limited to a restricted area of the Pacific Northwest. Here, we report on the first records of H. aestivaria for eastern North America from three widely separated urban centers in eastern Canada during 2019-2020.

A definitive species list is the foundation of biodiversity and conservation work. As we deal with massive climatic changes in the Anthropocene, knowing which species make up our diverse ecosystems will be critically important if we wish to protect and restore them. The Lepidoptera, moths and butterflies, are the fourth-largest insect order in terms of global diversity, with approximately 158,000 described species. Here we report the distributions of 5431 species that occur in Canada and Alaska, as well as 53 species that have been reported from the region but not yet verified. Additionally, 19 species are listed as interceptions or unsuccessful introductions, and 52 species are listed as probably occurring in the region. The list is based on records from taxonomic papers, historical regional checklists, and specimen data from collections and online databases. All valid species and their synonyms, and all Nearctic subspecies and synonyms are included, except for butterfly subspecies (and their synonyms) that have never been reported from the region. The list is presented in taxonomic order, with the author, date of description, and original genus provided for each name.

Our checklist is now published, and is available from Pensoft, as a hardcover book for purchase or as an open access PDF. We hope you find it useful in your work. Although our list is "done", all such lists are forever works in progress, as new information comes "to light". Please send new records, corrections and updates via email to the lead author.

The detailed, annotated list has been compiled and a manuscript is making its way through the publication process. It lists 5400 species confirmed as occurring in Canada and AK, and over 300 species that have been reported previously in error.
