Introduction
This Web site is a "work in progress," consisting of information on the known distribution of stoneflies (Plecoptera) in the United States. Distribution maps and county checklists were created by extracting information on stonefly distribution from publications listed in References. Users of the Web site should recognize that lack of a confirmed sighting in a given county does not necessarily mean that the species is absent from that county.

Because it is a "work in progress," the Stoneflies of the United States Web site is constantly being updated. Additional families, photos, and species accounts will be added as funds and time permit, and distribution maps of species that are already covered are being updated as new county records are established. Distribution maps are currently limited to states of the conterminous United States. Persons with knowledge of additional publications or information on stonefly distribution are asked to contact one of the project coordinators at the addresses given below.
