Acroneuria frisoni Stark & Brown .

This is the most frequently collected Acroneuria in the southern Midwest. It is known from the western Ozark Mountains through Maryland, north to Ontario and south to North Carolina ( Chabot 2010). Although this species once inhabited streams in the till plain of north central Indiana and Illinois ( Grubbs 2004, DeWalt et al. 2005), there are no recent records from this region.

We have since located one population in northeastern Indiana at the till plain/drift plain boundary. IN, Steuben Co., Fish Creek , 3.7 km E Hamilton along CR 775S, Douglas Woods Nature Preserve , 41.5327, -84.8688, 6/23/2006, R.E. DeWalt, 3♂, ♀ ( INHS) .
