Thermonectus marmoratus (Sunburst diving beetle)

Synonyms: Thermonetus marmoratus

Wikipedia Abstract

Thermonectus marmoratus is a species of diving beetle known by the common names sunburst diving beetle and spotted diving beetle. The beetle 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. This is the first ever recorded use of bifocal technology in the animal world.
