They are therefore clumsy in water (compared e.g. with the Dytiscidae or Hydrophilidae), and prefer to get around by crawling. The family consists of about 200 species in 5 genera, distributed wherever there is freshwater habitat; it is the only extant member of superfamily Haliploidea. They are also known as crawling water beetles or haliplids ...
Hydrophilus piceus is a species of beetles in the family Hydrophilidae, the water scavenger beetles. This very large aquatic beetle is found in the Palearctic and is known by the common name great silver water beetle .
The beetles could use the waves generated by their moving as a sort of radar to detect the position of object on the water surface around them. This technique could be used to detect prey or to avoid colliding each other. [4] The adult beetles carry a bubble of air trapped beneath their elytra. This allows them to dive and swim under well ...
