Differences between butterflies and moths Morphological differences Colouration of the wings
 Most butterflies have bright colours on their wings. Nocturnal moths on the other hand are usually plain brown, grey, white or black and often with obscuring patterns of zigzags or swirls which help camouflage them as they rest during the day. However many day-flying moths are brightly coloured, particularly if they are toxic. A few butterflies are quite plain, like the Cabbage White butterfly.
