The species Eretes australis (subfamily Dytiscinae) is one of the most common and widespread water beetles in Australia, as well as being the only species in the genus to be found in Australia, as well as found from Asia to Europe.

Also commonly known as the Padded Diving Beetle, this diving beetle is found in both permanent or temporary aquatic habitats. The adults of this species are strong fliers, sometimes attracted to lights at night and can end up in swimming pools.

They have a smooth, elongated-oval shaped body ranging up to 40 mm in length. The common name of Padded Diving Beetle, describes the adult male that have padded feet by which they grip the female when mating.
