They are also known as crawling water beetles or haliplids.

As mentioned below, crawling water beetles are not extensively studied; their interaction with humans is minimal.

As a result, the status of this population of Hungerford's crawling water beetles is uncertain at present.

Known populations of Hungerford's crawling water beetles are limited to cold-water streams in only five locations.

In Montmorency County, Michigan two more sites have yielded official records of Hungerford's crawling water beetles.

Like predaceous diving beetles (Dytiscidae), the crawling water beetles form an early offshoot of the Adephaga.

The only known population of Hungerford's crawling water beetles outside of the United States were discovered in the North Saugeen River near Scone.

Almost all known Hungerford's crawling water beetles live in a single location: the East Branch of the Maple River in Emmet County, Michigan.

Adult crawling water beetles use both their elytra and their hind coxae (the basal segment of the back legs) in air retention, while whirligig beetles simply carry an air bubble down with them whenever they dive.

As characteristic of all Haliplidae, the hindlegs of Hungerford crawling water beetles have a very distinctive and comparatively large coxal plates that cover most of the beetle's abdomenal underside as well as parts of its hindlegs.

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.

They are also known as crawling water beetles or haliplids.

Haliplids live in the aquatic vegetation around the edges of small ponds, lakes, and quiet streams.

The classification of haliplids as a separate group of Adephaga (primitive beetles) is unquestioned, and most entomologists believe they developed from terrestrial beetles separately from other types of water beetles.

The Haliplidae are a family of water beetles who swim using an alternating motion of the legs.

Cretihaliplus is a genus of beetles in the family Haliplidae, containing the following species:

B. J. van Vondel produced an updated catalogue of the known Haliplidae taxa.

Although most other Haliplidae are capable of flight, no observation has ever been recorded of a Hungerford's crawling water beetle flying.

The latter may be absent, but in the larvae of some Haliplidae it is tapering and ends in two prongs (which are not urogomphi though).

As with all Haliplidae, these specialized hindleg plates function as air storage devices supplementing the air carried under the wing covers.

Like all Haliplidae the imago of the Hungerford crawling water beetle is more or less ovoid, with a markedly convex upperside.

It is not yet resolved whether Haliplidae and Dytiscidae are closest relatives, or whether they originated independently from the basal Adephaga.

Hungerford's crawling water beetle (Brychius hungerfordi) is a critically endangered member of the Haliplidae family of water beetles.

These include whirligig beetles (Gyrinidae), Haliplidae, Noteridae, Amphizoidae, Dytiscidae, and Hydroscaphidae.

Among aquatic families - Dytiscidae, Haliplidae, many species of Hydrophilidae and others - the legs, most notably the last pair, are modified for swimming and often bear rows of long hairs to aid this purpose.
