Introduction
Butterflies and moths are insects that belong to the Lepidoptera order. Approximately 1,80,000 species of Lepidoptera are present in the ecosystem. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Lepidoptera is differentiated on the basis of scale that covers the bodies, wings, and proboscis. In the same way butterflies and moths differ widely on the basis of color and patterns. Both butterflies and moths play an important role in the maintenance of ecosystems as they act as pollinators and maintain the food chain or food web process but sometimes they create problems for farmers as their larval form destroys vegetation as their major source of food is plants. Apart from this, they have economical values also such as they produce silk.
Butterflies
Butterflies belong to the Papilionoidea superfamily and Lepidoptera order. Butterflies are distributed all over the world. Butterflies are active during the day and are usually brightly coloured or strikingly patterned. The life cycle of butterflies has four stages: egg, larva, pupa, and adult. The larvae and adults of most butterflies feed on plants, often only specific parts of specific types of plants.
Moths
Moths belong to a paraphyletic group of insects and belong to the order Lepidoptera. There are approximately 160,000 species of moth and most of them are undetermined. They are mainly nocturnal in nature. Difference between Butterflies and Moths

Facts about Butterflies and Moths
The Percentage of moths in the ecosystem is much more than butterflies. Moths occupy 81-96 percent of the total Lepidoptera order.
Both moths and butterflies undergo complete metamorphosis; this is the reason they are known as holometabolous.
It is not at all true that if you touch a butterfly’s wing and the ‘powder’ rubs off that the butterfly will not be able to fly. The powder is actually tiny scales and a butterfly sheds these ‘scales’ throughout its lifetime. Their flying capability does not depend on powder present on their scales.
The largest known butterflies in the world are the birdwings and the smallest known butterflies are the blues (Lycaenidae), which are found in North American and Africa. They have wingspans from 1/4 – 1/2 inches.
The largest known moths are the Atlas moths (Saturniidae) with wingspans as large as 12 inches and the smallest one known as pygmy moth belongs to the Nepticulidae family with wingspans as small as 3/32 of an inch.
Similarities between Moths and Butterflies
Both moths and butterflies belong to the same order i.e Lepidoptera.
Both butterflies and moths share common traits of having wings, an exoskeleton, a 3-parted segmented body with 3 pairs of legs, and one pair of antennae.
How do Moths Save Themselves from other Predators?
Moths may use camouflage or transparent patches on their wings to escape a predator's notice. Since they do not have any poisonous glands or protective covering to keep themselves safe from predators.
There are a lot of other fun facts about moths. There are more than 160000 species of moths. Male moths have the ability to smell the presence of any female moths even if they are located far from them.
In case the students want to know more about their characteristics, they can consult the reference books and other NCERT books that are full of information and pictures of animals belonging to different species.
The students have also the opportunity to join free classes on the website of Vedantu and they can also register for the masterclasses where they will get all kinds of benefits. The students will get the opportunity to experience live classes.
Are There Any Interesting Facts about the Butterflies that the Students Must Remember?
Butterflies are not only beautiful creatures but also they have some unique characteristics that make them stand out from the other species. The colour of the wings is the most fascinating thing about butterflies. Whereas the moth's wings are completely transparent in reality. More than Over 100,000 species of butterflies exist in the world and the variety of the patterns and colours that we can see on their wings provides enough evidence of the statement.
It is considered that butterflies do not live for long and most species of butterflies can only survive for a few weeks. The most fascinating information about butterflies is that they use their wings to protect themselves. They have two pairs of wings and those can protect them from other predators. The last and most important fact to remember here is that butterflies survive only on liquid food.
How Dust Helps Moths to Protect Themselves?
Moths do not have any other abilities to protect themselves from predators. Moths can only utilize the pair of wings they have. Since the wings of the moths are not as colourful as the butterflies, they do not have enough opportunity to protect themselves. The colour of the wings of most of the moths only helps them to protect themselves through the help of camouflage. The colour of the wings of moths mostly resembles the dust particles that we can perceive in our surrounding area. This is how the wings of the moths act as the protective shield. Moreover, other predators tend to avoid consuming moths if they are covered with dust.
FAQs on Difference Between Moth and Butterfly
1. What are the main differences between a butterfly and a moth?
Butterflies and moths, while both belonging to the order Lepidoptera, have several key differences. The most common distinctions are:
- Activity: Butterflies are typically diurnal (active during the day), whereas most moths are nocturnal (active at night).
- Antennae: Butterflies have thin antennae with a club-like tip. Moths have feathery or comb-like antennae without a club at the end.
- Wings at Rest: Butterflies usually rest with their wings held vertically together above their backs. Moths rest with their wings spread flat or folded in a tent-like shape over their body.
- Pupa Stage: A butterfly pupa is called a chrysalis, which is hard, smooth, and has no silk covering. A moth pupa is often enclosed in a silken cocoon.
- Colouration: Butterflies often display bright, vivid colours on their wings, while moths are typically coloured in dull, earthy tones for camouflage.
2. How do the antennae of moths and butterflies differ in structure and function?
The antennae are one of the most reliable ways to distinguish between a moth and a butterfly. A butterfly's antennae are thin and filamentous, ending in a distinct club or knob at the tip. They are used for sensing air movement and for balance during flight. In contrast, a moth's antennae are typically feathery or comb-like (pectinate) and lack the clubbed tip. This larger surface area is a specialised adaptation, particularly in males, for detecting airborne pheromones released by females, sometimes from several kilometres away.
3. How does the life cycle of a butterfly compare to that of a moth, especially in the pupa stage?
Both butterflies and moths undergo complete metamorphosis with four stages: egg, larva (caterpillar), pupa, and adult. The most significant difference occurs in the pupa stage. A butterfly caterpillar transforms into a chrysalis, which is an exposed, hardened casing that hangs from a surface. A moth caterpillar, however, typically spins a protective silken casing called a cocoon around itself before pupating. The pupa develops inside this cocoon, which provides extra protection and insulation.
4. What similarities do butterflies and moths share?
Despite their differences, butterflies and moths share fundamental biological traits because they both belong to the order Lepidoptera, which means 'scale wings'. Key similarities include:
- A four-stage life cycle (egg, larva, pupa, adult).
- Wings covered in tiny, overlapping scales.
- A three-part body consisting of a head, thorax, and abdomen.
- Three pairs of legs and one pair of antennae.
- A coiled feeding tube called a proboscis for drinking nectar.
5. How can you tell the difference between a moth caterpillar and a butterfly caterpillar?
Distinguishing between their larval forms can be tricky, but there are general guidelines. Butterfly caterpillars are typically smooth-skinned and may have spikes, but they are rarely hairy or fuzzy. In contrast, many species of moth caterpillars are distinctly fuzzy or hairy, sometimes with dense bristles. However, since there are many exceptions, this is not a definitive rule for all species.
6. Why are butterflies generally active during the day while most moths are nocturnal?
This difference in activity time is an example of niche partitioning, an evolutionary strategy that reduces competition for resources. By being active at different times, butterflies and moths target different food sources (day-blooming vs. night-blooming flowers) and face different predators. Butterflies use their bright colours for mating displays and to warn predators in daylight, while moths rely on camouflage and pheromones to find mates and avoid predation in the dark.
7. Is it true that a butterfly cannot fly if you touch its wings and the 'powder' rubs off?
No, this is a common misconception. The 'powder' on a butterfly's wings is actually thousands of tiny, overlapping scales that create its colour and pattern. While these scales are delicate, losing a small number from a light touch will not prevent a butterfly from flying. However, rough handling that removes a large number of scales or damages the wing structure itself can impair its ability to fly properly.
8. If both moths and butterflies are pollinators, how do their roles in the ecosystem differ?
Their different activity times mean they serve different types of plants. Butterflies, being active during the day, are attracted to brightly coloured (red, yellow, orange) and unscented flowers. They act as key pollinators for many daytime plants. Moths, being primarily nocturnal, are crucial pollinators for night-blooming plants. These flowers are typically pale or white, heavily fragrant to be located in the dark, and often have deep tubes containing nectar accessible to the moth's proboscis.
