A family of small aquatic beetles commonly called whirligig beetles, known for their rapid circular swimming behavior on water surfaces.
Scientific taxonomic name from Greek gyros 'circle' plus the Latin family suffix -idae. Named in the 18th century for the insects' characteristic spinning movements.
These beetles are aquatic acrobats with eyes split into two parts—one half watches above the waterline while the other watches below, letting them spot both predators and prey simultaneously!
