What is the federal conservation status assigned to the Hurd's Crawling Water Beetle, Brychius hungerfordi?
Answer
Federally listed as threatened.
The conservation status of certain water beetle species is directly linked to the precision of their habitat requirements. The Hurd's Crawling Water Beetle, *Brychius hungerfordi*, serves as a key example of this relationship. Due to its requirement for very specific lotic conditions—fast-flowing riffles over clean sand and gravel—its populations are highly restricted. This specificity has led to its official classification as federally listed as threatened. This designation underscores the vulnerability of species whose existence relies on maintaining a narrow set of physical and chemical parameters within their niche, especially compared to generalist families that can occupy nearly any pond environment.
