The Redspotted Sunfish (Lepomis miniatus) occurs in clear, low gradient, well-vegetated streams and backwater lakes. Although never abundant in Illinois, the distribution of L. miniatus has been reduced in the state due to habitat destruction. From 2004-2007, we sampled historical locations to determine the distribution, status, and habitat preferences of L. miniatus. We found the sunfish at seven of 27 sites sampled, and all of these sites had aquatic vegetation or physical structure present. Most of the historical sites where we failed to find L. miniatus did not have aquatic vegetation or large accumulations of woody debris. Because of its rarity and occurrence in low abundances, we recommended to the Illinois Endangered Species Protection Board that the Redspotted Sunfish be changed from state-threatened to state-endangered; this recommendation passed in 2009.
