The presence of larvae of Perlinella drymo in Michigan is documented for the first time. A total of 7 individuals were collected from Iron Creek, a tributary of the River Raisin watershed located in southeastern Michigan. Gut analysis of one specimen provided evidence for a carnivorous diet. The location from which larvae were collected indicate a preference during winter for stabilized undercut banks with little or no flow and accumulated organic debris upon sand and gravel substrate.
