Types that are aquatic in all life stages include whirligig beetles (Gyrinidae), Haliplidae, Noteridae, Amphizoidae, Dytiscidae and Hydroscaphidae
The diving beetle Thermonectus marmoratus has recently become notable when it was discovered that its aquatic larval stage has been found to have used in its principal eyes two retinas and two distinct focal planes that are substantially separated, in the manner of bifocals to switch their vision from up-close to distance, for easy and efficient capture of their prey, mostly mosquito larvae.
