Sorry--I just couldn't resist it! The clypeus of the cicada has always looked like the grille of an automobile to me. They always remind me of Edsels. (Click here for some nifty diagrams of cicada anatomy).
As you probably know, cicadas (like zillions of other true bugs, such as leafhoppers and spittlebugs) eat by sucking fluids from plants. When cicadas are young and live underground, they tap into roots; once they've got wings, they drink from stems. If you turn a cicada over, you can easily see the slender strawlike tube they jab into the plants.
The clypeus (which looks like a "nose" to some people, though I think it looks more like an automobile grille) contains the muscles that the cicada needs in order to suck plant juices.
Okay, maybe the Edsel isn't the best example. . . . How about one of these?
