This checklist includes all 176 described firefly species and subspecies known from the USA and Canada. It was assembled using specimen and occurrence records from sources including the published literature, digitized museum collections like Symbiota Collections of Arthropods Network (SCAN), and correspondence with researchers, among others.
To use this checklist, filter by fields such as species name (using either the genus or full species), taxonomic authority (the name of the person who described the species), or (both measures of extinction risk), type (life history strategy), whether females are flightless, or distribution (state or province). You may want to filter for neighboring states or provinces as well, as some places have been surveyed more intensively than others. (You can filter by multiple states/provinces at once.) You can then download or save a copy of your filtered checklist for your own reference (although note that the links will not be preserved).
Because multiple scientific names have changed in recent years, a column is included for recent synonyms. To search by recent synonyms, use the search box that is above the upper right corner of the table.
For species that have been assessed for extinction risk by the International Union for the Conservation of Nature (IUCN) Red List, links to assessments are provided, many of which include images and distribution maps.
