Focus on Butterflies (Van Gogh series) and analyze the Butterflies and moths.
Butterflies and moths, in the insect order Lepidoptera, are distinguished generally in several ways:  Butterflies are brighter in color and fly in the day.  Butterfly wings are not linked and fold together when they are in a resting position.  On the other hand, moths are generally duller in color, fly at night and have linked wings.  There are some exceptions, though, such as a few types of colored moths.
