Beetle
Coleoptera ( /koʊliːˈɒptərə/) is an order of insects commonly called beetles. The word "coleoptera" is from the Greek κολεός, koleos, meaning "sheath"; and πτερόν, pteron, meaning "wing", thus "sheathed wing". The reason for the name is that most beetles have two pairs of wings, the front pair, the "elytra", being hardened and thickened into a sheath-like, or shell-like, protection for the rear pair, and for the rear part of the beetle's body. The superficial consistency of most beetles' morphology, in particular their possession of elytra, has long suggested that the Coleoptera are monophyletic, but there is growing evidence that this is unjustified, there being arguments for example, in favour of allocating the current suborder Adephaga their own order, or very likely even more than one.

Famous quotes containing the word beetle:
“After the planet becomes theirs, many millions of years will have to pass before a beetle particularly loved by God, at the end of its calculations will find written on a sheet of paper in letters of fire that energy is equal to the mass multiplied by the square of the velocity of light. The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
—Primo Levi (1919–1987)
“The sense of death is most in apprehension,
And the poor beetle that we tread upon
In corporal sufferance finds a pang as great
As when a giant dies.”
—William Shakespeare (1564–1616)
“Ere the bat hath flown
His cloistered flight, ere to black Hecate’s summons
The shard-born beetle with his drowsy hums
Hath rung night’s yawning peal, there shall be done
A deed of dreadful note.”
—William Shakespeare (1564–1616)
