All the described butterfly and moth (Lepidoptera) species that are known to occur in Canada, Greenland, and the continental United States of America are listed. We have endeavored to include information from all publications up to the end of December 2022, as well as from a few publications that were in press at that time. All valid scientific names, from order to subspecies, are presented following the most recent available classification. For all species-level names, the current genus, species name, author, date, and original genus are listed. All available (and many unavailable) synonyms are listed, as well as hundreds of misspellings, emendations, misidentifications, and misapplied names published in the past century. In total, over 36,700 taxon names are included in the list.

Revision of European Ennominae moths, covering 202 species in 30 colour plates. Comprehensive text and rich illustration of genitalia structures for all species. Four new species are described and systematic checklist for entire European and adjacent regions' Geometridae fauna is provided.

Beetles are the largest and most studied order of insects, some of which are beneficial as biological control agents. Alphabetically lists all species and subspecies of beetles known to Canada and Alaska under their respective genus-group names. Includes a brief introduction for every family treated and an index to all supraspecific names.

This checklist of the Lepidoptera (butterflies and moths) of Alberta lists 2367 species reported to occur in the province, as well as 138 species whose occurrence in Alberta is probable. Each species entry includes adult flight time and distribution status in the Cordilleran, Boreal, and Grasslands ecozones, as well as references to taxonomic works and to the literature and public collection sources of the records. Detailed notes on taxonomy, nomenclature, distribution, habitat, and biology are given for 1524 of the listed species. An additional section provides details on 171 species erroneously reported from Alberta in previous works. The authors hope it will be a useful resource for anyone carrying out species-level work on Lepidoptera in western Canada, or taxonomic work on Lepidoptera in general. An introductory section provides a general overview of the order Lepidoptera and the natural regions of Alberta, and the history and current state of knowledge of Alberta Lepidoptera. Each of the 63 families (and selected subfamilies) occurring in Alberta is briefly reviewed, with information on distinguishing features, general appearance, and general biology. The list is accompanied by an appendix of proposed nomenclature changes, consisting of revised status for 25 taxa raised from synonymy to species level, and new synonymy for 20 species-level and one genus-level taxa here considered to be subjective synonyms, with resultant revised synonymy for one taxon and formalization of seven new combinations.

The second volume on tineid moths from Europe presents information for the identification of 103 species. For each species, a diagnosis, illustrations of moths, male and female genitalia as well as information on life history and distribution is given.

"Moths and butterflies (Lepidoptera) are one of the most diverse and economically important groups of insects, with approximately 157,000 species worldwide. This book establishes a definitive list of the species that occur in BC, and clarifies erroneous records in past works. It provides a knowledge baseline that will be useful to resource and conservation managers, biodiversity researchers, taxonomists, amateur collectors, and naturalists."--Back cover.
