Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

North America: lower Great Lakes and Mississippi River basin from Ontario in Canada and from New York to southeastern Minnesota in USA and south to northern Alabama and eastern Oklahoma, USA; upper and middle Mobile Bay drainage in Georgia, Alabama and southeastern Tennessee in USA.

Biology     Glossary (e.g. epibenthic)

Inhabits sand-bottomed to rock-bottomed pools and runs of creeks and small to medium rivers. Also found in impoundments (Ref. 5723, 10294). Adult feeds on small benthic invertebrates, especially microcrustacea and midge larvae (Ref. 10294).
