 Indeed, of the five known locations in which Hungerford's crawling water beetles have been found, two are within the Mackinaw State Forest, one along the East Branch of the Black River and the other in Van Hetton Creek.The Van Hetton Creek identifications are significant as they represented a new location beyond those originally identified when the Hungerford's crawling water beetle was categorized as endangered in 1994.This suggests that the rare beetle may occur in other sites as yet undiscovered elsewhere in Mackinaw State Forest.
