So What Is The Difference Between A Moth And A Butterfly?

the basics are as follows:

Similarities

• Scales on wings
• Both undergo complete metamorphosis from egg to caterpillar, chrysalis (cocoon) to adult
• Both have compound eyes, although the types differ

Differences

• Antenna size, shape, and type
• The folding of wings (resting posture)
• Moths have a frenulum, which joins the forewing to the hindwing. Butterflies do not
• Primarily diurnal (butterflies) vs. nocturnal (moths)-- though not always
• A moth makes a cocoon and a butterfly makes a chrysalis
• Butterflies tend to have a more slender body than moths
• Diet

There are no universal characteristics that divide butterflies and moths, so the identification of both can be quite difficult.
