The Alberta Lepidopterists' Guild (ALG) is a non-profit society made up of amateur and professional Lepidopterists. Our objective is to support and encourage the study and appreciation of Alberta Lepidoptera (butterflies and moths). We coordinate research projects, facilitate the exchange of information among members, and host events where people can collect and look at Lepidoptera and exchange information and ideas. We have an elected executive, and hold at least one annual general meeting to handle society business. We also host a members-only electronic bulletin board, and numerous scientific and social events throughout the province.

Alberta is a province in western Canada which includes a diverse range of habitats, including mountains, boreal forest, and prairie. Over 3000 species of butterflies and moths are thought to live here; so far about three-quarters of these are known.

New Publication by ALG Members

An annotated list of the Lepidoptera of Alberta, Canada.
ZooKeys 38 (2010) Special Issue. doi:10.3897/zookeys.38.383

Four ALG members have recently published an annotated checklist of Alberta Lepidoptera. It 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 over 1500 of the listed species. An additional section provides details on 171 species erroneously reported from Alberta in previous works. 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.

This site was last updated 28 November 2011.
It was written primarily by Greg Pohl, with submissions from other ALG members.
This site was designed by Jon Elofson and is edited by Heather Proctor (hproctor[at] and Danny Shpeley.

2011 ALG Wolley Dod Award

Jan Scott's discovery of Dioryctria auranticella and D. rossi in Medicine Hat was voted the winner of the 2011 Wolley Dod Award. The previous distribution records for D. auranticella were southern BC in Canada and in the U.S. as far east as North Dakota and south to New Mexico, and for D. rossi southern BC and south to New Mexico and Texas.

The Wolley Dod award is given annually for the most significant Alberta Lepidoptera discovery of the season.
