Butterfly or moth
Butterfly and moths are the most popular and easily recognizable of insects.Together,the two groups make up a large group (or Order) of insects known as the Lepidoptera (from the Greek words for “scale” and “wing”). The Order is divided into families of butterflies and moths, containing about 150,000 know species. The division of Lepidoptera into butterflies and moths is an artificial one, based on a number of observable differences. For example, most butterflies fly by day and most moths fly by night; many butterflies are brightly coloured and many moths are dull-coloured ; most butterflies hold their wings upright over their backs, while most moths rest with their wings flat; butterfly antennae are knobbed at the but moth antennae are either feather-like or plain. But despite these rules, there is not one single feature that separates all butterflies from all moths.
