The beetle has recently become notable when it was discovered that its aquatic larval stage is the first ever recorded use of bifocal technology in the animal world. The beetle uses 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.
