Oreodytes humboldtensis
Oreodytes humboldtensis is a species of predaceous diving beetle in the family Dytiscidae, described by Zimmerman in 1985. As a member of the genus Oreodytes, it belongs to a group of small diving beetles primarily associated with running water habitats. The species epithet suggests a connection to the Humboldt region, likely referring to Humboldt County or the broader Humboldt Bay area of coastal northern California. Like other Oreodytes species, it is presumed to be an aquatic predator in freshwater systems.
