In which Michigan river systems has the federally threatened Brychius hungerfordi specifically been documented?

Answer

The Huron River system and the Grand River basin.

The known geographical distribution for the highly specialized Hurd's Crawling Water Beetle (*B. hungerfordi*) is geographically restricted, primarily focusing on specific river systems within the Great Lakes region of North America. Focusing specifically on documentation within the state of Michigan, records confirm the beetle's presence in streams located in the southern part of the Lower Peninsula. The concrete examples provided for confirmed sites point specifically to the Huron River system and the Grand River basin. These sites meet the required lotic conditions: fast-flowing water over the necessary sand and gravel substrate, demonstrating the tight correlation between the species' precise requirements and its actual documented presence.
