Moth Vs Butterfly: How To Tell The Difference, Pictures & Examples

Moth versus butterfly – what sets apart these widely recognized groups of insects? Here, you’ll discover a comprehensive manual detailing the disparities between moths and butterflies, accompanied by captivating imagery, intriguing facts, and illustrative examples.


Moths and butterflies, both belonging to the insect order Lepidoptera, often exhibit resemblances to each other. Interestingly, butterflies have evolved from moths.

Both moths and butterflies undergo a four-stage life cycle known as complete metamorphosis, transitioning from eggs to mature winged adults. So why are moths and butterflies distinguished within the Lepidoptera order?

One of the most well-known distinctions is that moths are predominantly active at night (nocturnal), while butterflies are active during the day (diurnal).

Nonetheless, there are exceptions to this general rule, and this comprehensive guide provides practical insights on how to differentiate between these captivating winged creatures.

Below, you will find an inventory of the primary differences between moths and butterflies. However, please note that exceptions to these characteristics exist, which we will address later in this guide.

Moth Vs Butterfly: Discerning the Contrast

  • The majority of butterflies are diurnal, whereas most moths are nocturnal.
  • Moths often possess wings with subdued hues, while butterflies typically showcase vibrant and conspicuous colors.
  • Moths exhibit feathery antennae, often tapered or resembling leaves.
  • Butterflies possess slender, hairless antennae that culminate in a ball or club.
  • When at rest, moths either fold their wings flat against their bodies or rest with their wings open, touching the surface beneath them.
  • Butterflies, on the other hand, usually rest with their wings held together behind their bodies or bask with their wings spread wide open but not in contact with the surface they rest upon.
  • During the pupal stage, moths create silk cocoons, while most butterflies form chrysalises with sturdy outer coverings.
  • A row of hair-like structures called frenulum connects the fore and hind wings of moths, a feature absent in most butterflies.

Elaborating on the Differences Between Moths and Butterflies

As established, the primary behavioral distinction between moths and butterflies is that most moths are either nocturnal or crepuscular (active at dawn and dusk), while the majority of butterflies are diurnal.

However, exceptions exist, with certain moth species displaying daytime activity, and a handful of butterflies being active at night. Examples of both can be found later in this guide.

Statistical data supports this distinction, revealing that there are approximately nine moth species for every one butterfly species. Additionally, researchers estimate that between 75% and 85% of Lepidopteran species exhibit nocturnal behavior.

Therefore, while the patterns of nocturnal or diurnal flight provide a useful indication of whether an insect is a moth or a butterfly, it is not definitive. Some moths are diurnal, while some butterflies are nocturnal.

To accurately identify these captivating insects, one must consider the key distinctions in their physical attributes.

Moth Vs Butterfly: Comparing Wing Coloration

In general, moths tend to possess wings adorned with muted hues, whereas butterflies often boast colorful patterns.

This adaptation aligns with their respective lifestyles: moths require camouflage during their inactive daytime periods, rendering bright colors unnecessary for nocturnal creatures. In contrast, butterflies employ vibrant hues to attract mates, while moths primarily rely on pheromones.

Interestingly, moths that are active during the day typically exhibit brilliantly colored wings.

The brightly colored wings of butterflies serve two primary purposes:

Mate attraction: Vivid colors can play a significant role in mate selection, as they signal good health and genetic fitness. Males with vibrant colors are often more appealing to females, increasing their chances of successful mating and passing on their genetic traits.

Warning signals: Some butterflies use bright colors as a form of aposematism, serving as a warning signal to potential predators. These colors indicate that the butterfly is toxic or unappetizing, discouraging predators from consuming them.

In many species, there is a noticeable disparity in appearance between males and females. An example of this can be observed in the world’s largest butterfly, the Queen Alexandra’s birdwing (Ornithoptera alexandrae). The male of this species exhibits vivid colors, while the female, although larger in size with a wingspan of up to 28 centimeters (11 inches), has a comparatively dull appearance.


Moths typically possess antennae adorned with feathery projections and pointed tips. In contrast, butterflies have slender antennae that lack hair and terminate in a spherical shape or club-like structure.



The manner in which moths and butterflies position their wings when at rest provides another means of differentiation.

Moths tend to flatten themselves against surfaces, either folding their wings back against their bodies or extending them open, touching the resting surface.

Butterflies, on the other hand, tend to hold their wings straight back or open wide, with a noticeable space between each wing and the surface they rest upon.

It’s important to note that there are exceptions to these behaviors, such as skippers (butterflies belonging to the Hesperiidae family), which fold their wings behind them like moths.


A distinguishing feature between moths and butterflies lies in the connection between their fore and hind wings. Moths possess a row of hair-like structures called a frenulum, which joins their wings together. In contrast, most butterflies lack this characteristic.


Moths typically possess robust and hairy bodies, possibly an adaptation to evade bats’ echolocation. In comparison, butterflies tend to have slender and smoother bodies.

Cocoon Vs Chrysalis

During their pupal stage, moths construct cocoons using silk, within which they undergo metamorphosis from caterpillars into adult moths.

In contrast, most butterflies form chrysalises, which feature a hardened outer skin. These chrysalises serve as protective casings during the transformation from caterpillar to butterfly.

Although both cocoons and chrysalises act as protective coverings during the pupal stage, they differ in structure. Cocoons are woven silk casings created by moth caterpillars and certain other insects, while chrysalises are rigid cases formed by butterfly caterpillars without the use of silk. The exoskeleton of the caterpillar hardens, providing a protective layer for the developing butterfly within.

However, exceptions exist, such as hawk moths, which pupate in exposed pupae rather than silk cocoons.


To fully grasp the distinction between moths and butterflies, it is necessary to delve into the evolutionary history of both insect groups.

Surprisingly, moths appeared millions of years before butterflies, and butterflies subsequently evolved from moths.

Moths and butterflies belong to the order Lepidoptera, which translates to “scale wing.” This name refers to the numerous tiny scales covering their wings and bodies.

Other insect orders include Diptera (flies), Hymenoptera (bees, wasps, and ants), and Coleoptera (beetles).

Like all insects, moths and butterflies have three body segments: the head, thorax, and abdomen. They undergo a four-stage life cycle consisting of eggs, larvae (caterpillars), pupae (chrysalises or cocoons), and imago (adult moths or butterflies).

Butterflies form a distinct group within Lepidoptera called Papilionoidea, which is a superfamily encompassing various butterfly families, including Papilionidae (swallowtails and birdwings) and Nymphalidae (brush-footed butterflies).

It is worth noting that there is ongoing debate regarding the inclusion of moth-like Hedyloidea within Papilionoidea.

Moth and Butterfly Diversity

Lepidoptera comprises approximately 180,000 known species*. Out of these, only around 10% are butterflies, while the remaining 90% are moths.

The majority of moths and butterflies are found in tropical regions, although they can be found on every continent except Antarctica.

*As of the current update in April 2023, the Catalogue of Life lists 159,657 living species, while the 1999 edition of the Handbuch der Zoologie lists 174,250 species.

Together, moths and butterflies constitute around 1% of all known organisms.

Evolution of Moths and Butterflies

Moths have existed since the time of dinosaurs, making them ancient creatures. Butterflies, however, emerged more recently, approximately 55 million years ago, following the extinction of non-avian dinosaurs.

The first moths appeared during the Jurassic Period, coexisting with dinosaurs. The earliest known moth, Archaeolepis mane, dates back to around 190 million years ago in the Early Jurassic.

During the Cretaceous Period, flowering plants began to emerge, leading to a coevolutionary relationship between Lepidoptera and flowering plants. Butterflies and moths played a crucial role in pollination, while the plants provided them with nectar as a food source.

Proboscises, the curled tongue-like mouthparts used for sipping nectar, began to develop in adult lepidopterans during the Cretaceous. This feature is prevalent in most modern butterflies and moths.

Butterflies made their appearance around 55 million years ago, around 10 million years after the extinction of dinosaurs.

Interestingly, butterflies evolved from moths. Due to the prior existence of different moth groups, some moths are more closely related to butterflies than they are to other moth groups.

Moths Active During the Day

Several moth species display daytime activity, defying the typical nocturnal behavior associated with moths. Some notable examples include:

  • Hummingbird Hawk-Moth (Macroglossum stellatarum): Found in Europe, Asia, and parts of Africa, these moths hover like hummingbirds while feeding on flower nectar.
  • Cinnabar Moth (Tyria jacobaeae): Recognizable for its striking red and black markings, this moth is commonly found in grasslands and meadows. It is native to Eurasia but has been introduced to Australia and North America.
  • Six-Spot Burnet (Zygaena filipendulae): This European day-flying moth displays vibrant blue-green wings adorned with six red spots, typically found in grassy habitats.
  • White-lined Sphinx Moth (Hyles lineata): Known for its large size and swift flight, this moth is often mistaken for a hummingbird. It is active during the day and ranges from Central America through Mexico to most parts of the United States.
  • Clearwing Moths (Sesiidae family): These day-flying moths have transparent wings and slender bodies, often resembling wasps or bees.

Butterflies Active During the Night

While butterflies are predominantly diurnal, a few species have adapted to be active during the night. Some examples include:

  • Northern Pearly Eye (Enodia anthedon): Found in North America, this butterfly exhibits activity during dusk, dawn, and occasionally at night.
  • Common Glider (Neptis sappho): Active during twilight and the early night, this butterfly is typically found in Europe and Asia.
  • Chocolate Demon (Ancistroides nigrita): Native to Southeast Asia, this nocturnal butterfly resides in forested areas and displays captivating wing patterns.
  • Malayan Night Fliers (Elymnias caudata): These butterflies, found in Southeast Asia, are active during dusk and throughout the night. They are renowned for their striking wing patterns.

Understanding the distinctions between moths and butterflies allows us to appreciate the incredible diversity and adaptations within the Lepidoptera order. Whether they flutter in daylight or grace the night skies, these enchanting insects continue to captivate our imagination.
