Beetles are the group of insects with the largest number of known species. They are classified in the order Coleoptera (; from Greek κολεός, koleos, "sheath"; and πτερόν, pteron, "wing", thus "sheathed wing"), which contains more described species than in any other order in the world.
In 1992, Ronald Weasley accidentally squashed a beetle which he was supposed to be Transfiguring into a button, due to his broken wand producing a large amount of smoke, which obscured his vision. This annoyed Professor McGonagall, the Transfiguration teacher.
