A member of the family Gyrinidae; a whirligig beetle, a small aquatic insect known for spinning rapidly in circles on water surfaces.
Formed from Gyrinidae (the family name, from Greek gyros 'circle') with the suffix -id meaning 'member of.' Named for the beetles' distinctive gyrating behavior.
Whirligig beetles are nature's original spinners—they can detect vibrations through the water using special sensors and actually hunt by reading ripples from their own spinning motion!
