Do insects have a sense of hearing?

They certianly make a lot of noise - so i suspect some speicies do. 
But what about a beetle or a bee?
And if the answer is yes - how do they hear? Do they have ears?

Yes. They hear by means of ears (a tympanic membrane with nerve fibers attached) and by very delicate hairs (trichobothria, sensilla) that respond to vibrations in the air. Sound is very important to insects in courtship.
