Moths and butterflies are similar insects both of which have broad, colourful wings and long tubular mouthparts to feed on nectar.  A major difference between the two groups is that butterflies are active by day - diurnal - and moths are active by night - nocturnal.  That seems like a nice easy distinction which has only one problem, some moths, such as the Mistletoe Moth, are daytime insects.  These beautiful creatures look very much like butterflies, even to the extent that they rest with their wings together, as butterflies do. 

The Mistletoe Moth name comes from the fact that the caterpillars will feed on no other species of plant.  This is a common feature of mistletoes and virtually all Australian species are the preferred food plant of at least one species of butterfly or moth.
