This list has 77 species of stoneflies that currently reside in the state or did so historically. It was last updated by Dr. R. Edward DeWalt on 7 March 2008 and is based on DeWalt et al. (2005). All such lists of species are incomplete. This list is not meant to serve as a source of valid names for Illinois Plecoptera, only as a ongoing tally of the species reported from the state as published in the literature. Go to Plecoptera Species File for valid names. Common names are from Stark et al. (1998) and suggested Illinois conservation status ratings are from DeWaltet al. (2005). Please see sources below.
