Flower Flies are conspicuous and critical part of the Nearctic fauna.
Currently, 891 species of Flower Flies have recorded from the region and are
distributed among 89 genera.
The last revision of the Nearctic Flower Flies was by Williston (1887).
Since that time there have been numerous new species described, some
generic revisions, a couple partial revisions (such as Curran 1925 or
Vockeroth 1992), a few regional treatments (Metcalf 1913 (Ohio), Fluke
1922 (Wisconsin) and Telford 1939 (Minnisota)). The last published catalog
was in 1965; more up-to-date listing of taxa and their names will be found
at this WWW site. A basic review and key to genera and the literature is
provided by Vockeroth & Thompson (1987).
This project will provide HTML keys to the genera and species; a faunistic
analysis, links to the appropriate genus and species pages, as well as an
index to the literature.
