Insects with hard wing covers and six legs, or to move quickly and busily around like The Beatles did.
From Old English 'bitela,' related to 'bite' due to the insect's strong jaws, becoming 'beetle' by the 1300s; also used as a verb meaning 'to hurry about busily.'
There are about 400,000 species of beetles on Earth—they make up 25% of all known animals, meaning if you met four animals randomly, one would likely be a beetle, making them Earth's most successful survivors!
