Difference Between Moth and Butterfly

From a single glance, it would be rather hard to tell apart a moth from a butterfly because of their general shape and size. Furthermore, these two organisms have many things in common. For instance, both are members of Class Insecta and order Lepidoptera. Both have an exoskeleton, and both have a 3-part-segmented body with 3 pairs of legs. To make matters more confusing, both have minute scales that cover their entire body and wings. However, that is where the similarities between the two end.

Moths

Butterflies

Behaviour

Moths are nocturnal – active at night

Butterflies are Diurnal – active at day

Wings

Moths flatten out their wings when at rest

Butterflies fold their wings back when at rest.

Pupal Stage

Moths make cocoons from silk

Butterflies make chrysalis that is hard, smooth and does NOT comprise silk.

Anatomy

Moths have a structure called the Frenulums, which join the forewing and hind wing

Butterflies have no frenulums

Antenna

Moths have stout and fuzzy antennas with a feathery or comb-like appearance

Butterflies have long, slender antennas with club-shaped tips

Colours

Moths have comparatively duller colours than butterflies

Butterflies sport more vibrant colours

Size

Moths are generally smaller compared to butterflies

Butterflies are generally larger compared to moths

Species and Distribution

Moths make up between 89-94 per cent of order Lepidoptera

Butterflies only make up between 6-11 per cent of order Lepidoptera

Please note – there are some exceptions to the aforementioned difference. For example, though moths are nocturnal, some moths such as the hummingbird moths feed on flowers during the day time.
