## Summary

It is important to know which species occur in Canada to be able to protect them. The goal of this checklist is to identify all known species of flies in Canada. Results indicated that we have 9777 known species of flies in Canada, among 118 families. When considering all known species in Canada, flies represent about 12% of species, making them one of the most diverse groups. On average, each species of flies occurred in 3.2 regions (provinces or territories) in Canada. English and French common names were developed and standardized for all species. This checklist is a fundamental piece of work that will guide the assessment of the conservation status of those species.

## Résumé

Il est important de connaître quelles espèces sont présentes au Canada afin de pouvoir les protéger. Le but de cette liste est d'identifier toutes les espèces connues de mouches au Canada. Les résultats indiquent que nous avons 9777 espèces connues de mouches au Canada, parmi 118 familles. En considérant toutes les espèces connues au Canada, les mouches représentent environ 12% des espèces, en faisant l'un des groupes les plus diversifiés. En moyenne, chaque espèce de mouches se retrouvait dans 3,2 régions (provinces ou territoires) au Canada. Des noms communs en français et en anglais ont été développés et normalisés pour toutes les espèces. Cette liste représente un travail fondamental qui aidera l'évaluation du statut de conservation de ces espèces.
**Introduction**

The first step in preventing the loss of species is to identify those that exist in Canada, and where they occur. For many groups of species in Canada, there is not yet enough information compiled to create a species list, meaning that we do not know which species exist in the country. Without knowing which species exist in Canada and where they occur, it is difficult to predict the impact of humans and anthropogenic changes on ecosystems and species. Moreover, if not documented, species might disappear without us noticing.

In 1996, the wildlife ministers in Canada signed the Accord for the Protection of Species at Risk, making the commitment to "monitor, assess and report regularly on the status of all wild species". This ambitious goal is the mandate of the program on the General Status of Species in Canada. A few years later, the federal government confirmed the commitment made under the Accord by including in the Species at Risk Act section 128 that stipulates that "five years after this section comes into force and at the end of each subsequent period of five years, the Minister must prepare a general report on the status of wildlife species". Reports from the Wild Species series serve as the basis to fulfill both requirements. These reports inform Canadians about the status of species in the country, and provide information that can help prevent species in Canada from becoming extirpated as a consequence of human activity.

In total, 50 534 species were included in the most recent report, Wild Species 2020 (Canadian Endangered Species Conservation Council, 2022), representing the most complete understanding we have ever had on the status and distribution of wild species in Canada. The report included groups such as slime moulds, fungi, plants, corals, cephalopods, spiders, several insects, sea stars and vertebrates. Some families of flies (order Diptera) were also included. In total, 72 families of flies were included, representing 5 172 known species in Canada. The Wild Species 2020 report however indicated that there is an estimated total number of about 8 535 described species of flies in Canada, so at least 3 363 were missing and had no lists of species.

Similarly, a recent study on the Diptera of Canada (Savage et al., 2019) estimated that there are probably in total 116 families and 9 620 described species of flies in Canada. The study also mentioned that there is also probably a large number of species of flies that are not known to science or not yet discovered in Canada.

The goal of this checklist is to develop a list of all known species of flies in Canada. This list will be essential for the assessments of the conservation status of those species in the next Wild Species reports.

**Methodology**

Each expert was assigned a group of families (Table 1). For each family, the expert searched for the available information that could be helpful to create the list of species. Only species confirmed within a province or a territory in Canada were included. The presence of the species was confirmed by a variety of sources, including for example databases of museum collections and references. Only species known to science were included. Undescribed species were not included. Undescribed species that are part of a complex of species were regrouped under the described parent species. Subspecies were also regrouped under the described parent species (the data associated with them was considered while determining the distribution of the full species).

The higher classification is based mostly on Savage et al., 2019. All taxonomic levels within the taxonomic hierarchy are ordered alphabetically. The authority is also provided for each taxonomic level.

For each species, the following information is provided: valid scientific name, authority of the valid scientific name, scientific names that are synonyms with their corresponding authority, the known distribution in Canada, the English common name and the French common name. In each section, the species are listed alphabetically based on their valid scientific names. When the authority is written in brackets, it means that the scientific name has changed compared to the original description. To specify the distribution of the species, the abbreviations of the regions (Table 2) indicate that the presence of the species is confirmed in the specific provinces or territories, and the hyphen indicates that the species is not known to occur.

Common names represent an important communication tool for engaging with the public on the diversity of species in Canada and on the need to conserve them. Common names were developed

using a standardized methodology (National General Status Working Group, 2025). To summarize the methodology, contracts are given to English experts to provide suggestions for English common names, and contracts are given to French experts to provide suggestions for French common names. The suggested common names are then reviewed by the Canadian Wildlife Service (Environment and Climate Change Canada), especially to ensure that the taxonomic logic of the common names is rigorous. The suggested common names are then reviewed by the Terminology Standardization Division of the Translation Bureau of the Government of Canada. This step includes a linguistic review of the common names, both in English and French. If appropriate, it also provides an opportunity to align the English and French common names, so that they have a similar meaning. The common names were thus not done by one person solely. The common names will continue to be reviewed and updated in the future (National General Status Working Group, 2024).

## Results

We were able to confirm the presence of 9777 species of flies in Canada. These species are found among 118 families (Table 3).

The three provinces that had the highest number of species were Ontario (4728 species), British Columbia (4544 species), and Quebec (4106 species) (Figure 1). On average, each species of flies occurred in 3.2 regions (provinces or territories) in Canada. In total, 3614 species occurred in only one region in Canada, and 53 species occurred in all the 14 regions (Figure 2).

English and French common names were developed for all species of flies occurring in Canada. Most of the time, the families were the taxonomic level used to standardize the common names (Table 4). This means for example that the part of the common name that describes the taxonomic group is "Long-bodied Crane Fly" for all species in the family Cylindrotomidae.

Most species had no common names, and they were created for this publication. Some common names that already existed were also adapted to use the same approach for all families. The rationale of the approach used is to make the common names as accessible to the public as possible. Some families have hundreds of genera, and it would be difficult to understand that they all are closely related if they would have completely different names. Moreover, most of the families already have well established common names.

## Discussion

We have about 80 000 species in total in Canada, excluding viruses and bacteria. The 9777 species of flies thus represent 12% of all species of Canada, making the flies one of the most diverse groups of species in Canada. Several other species of flies will certainly be discovered in the future in Canada. Many species are not yet described or are not known to science.

The diversity of flies follows about the same pattern than all other species in Canada. In the Wild Species 2020 report, the three regions that had the highest number of species were Ontario, British Columbia, and Quebec, which is the same for the flies. Many species occurred only in a few regions in Canada. Species with smaller geographic distributions may be more restricted to specific habitats. However, knowledge is lacking on flies and their distribution will be improved with more survey work.

The next step will be to assess the conservation status of the species of flies in Canada. These assessments will be released in the report series Wild Species: The General Status of Species in Canada (www.wildspecies.ca).

## Acknowledgments

We would like to thank all the linguistic experts from the Translation Bureau for their involvement in the revision of the common names: Anh Thu Pham, Zacharie Vaillancourt, Marie D'Aoûst, Mandy Silver, and Karine Rondeau. We would like to thank Caroline Gagné and Micaela Correa for their help with the management of the contracts required to build this checklist, and we would like to acknowledge the work that Micaela Correa has done to reorganize some Excel files. We would like to thank also Scott Gilmore who provided further updates on the checklist. We would like also to thank other experts who were involved in draft versions of common names or in previous versions of the list of species for some families of flies: Anne-Sophie Caron, Julia Mlynarek, Andrew Young, Véronique Bellavance, Stéphanie Boucher, Sabrina Rochefort, Patrick Schaefer, Veronica Bura, Michelle Locke, Sarah Matheson, Jeff Skevington, Doug Currie, Aynsley Thielman, Fiona Hunter. Finally, we would like to thank all the members of the National General Status Working Group for their support in developing checklists of species in Canada.
