The moth members of this Order of insects include a large number of diverse families. Moth groups include micro moths, leaf miners, clothes moths, plume moths, ermine moths, burnets, geometrids, silk moths, sphinx moths, tiger moths, wasp moths, noctuids, underwings and many others.
Many male moths have elaborate antennas to comb the evening air for molecules of pheromones emitted by potential mates. The intricate network of sensillum hairs filter these scent molecules from the air and allow the moth to find the object of his desire at a considerable distance. Moths are not the only insects with finely tuned chemoreceptor. Certain beetles also expose their antennae to the scent soup of the evening air.
