What Do Moths Eat? Moths are insects categorized under the Order Lepidoptera, which they share with butterflies. Over 160,000 moth species exist in the world today, with many of these yet to be described scientifically.
Moths eat many different things. A majority of the moths dine on leaves and flowers from plants. Some caterpillar moths feed on seeds, fruit, animal products like fur or beeswax. In contrast, the carnivorous ones consume aphids and other soft-bodied insects.
This page will shed light on the different types of moths, pointing out what they eat and how they hunt. We will also explore insight into when moths eat, how often they eat, what predates on them, and their role in the animal food chain.

What Do Atlas Moths Eat?
Atlas moth (Attacus Atlas) is one of the largest insects on the earth. Their wingspan can extend up to 12 inches wide, which explains why they are considered giant moths.
- This moth species is native to the Southeast Asian region. They are famed for the markings on their wings’ upper areas, which resemble a cobra’s head.
- The Atlas moth caterpillars can grow to 5 inches long, thanks to their regular intake of cinnamon leaves, citrus fruits, guava, and cherry trees.
- Adult atlas moths do not eat at all. Food consumption at the caterpillar stage can sustain them during their pupal and adult stages.
Do Moths Eat Bugs?
Although you may think that all moths are herbivorous, in reality, many species have been documented to eat insects. Depending on the species, some moths may follow a meat-filled diet during their larval stage, while others may do so when they are fully grown adults.
Some moths have even been found to engage in cannibalism, sometimes eating their own siblings. Below is a list of some of the most prominent moths that are known to eat meat.
What Do Harvester Moths Eat?
The meal plan of fully-grown harvesters mainly consists of them draining and consuming the fluids of damp sand, aphids (bugs that secrete honeydew, a sweet and sticky liquid), carrion, and more. On the other hand, harvesters still in the caterpillar stage follow a strictly carnivorous diet, eating small insects such as woolly aphids.
What Do Cherry Gall Azure Moths Eat?
In their caterpillar stage, cherry gall azures almost always only eat the galls – abnormal growths that occur on plants of the black cherry shrubs and many other flowering plants.
However, in their pupa stage, these azures have also been documented to consume the eriophyid mites (microscopic parasitic arthropods) that cause the formation of the galls.
What Do Planthopper Parasite Moths Eat?
In their larvae stage, planthopper parasite moths, as their name suggests, have been shown to drain and drink the fluids of insects known as planthoppers (referring to any of the 12,000+ species in the infraorder Fulgoromorpha).
What Do Scale-feeding Snout Moths Eat?
In their larvae stage, as their name suggests, the main part of the diet of scale-feeding snout moths are the eggs and young of insects known as scale insects due to their scaly physical appearance.
These moths can also eat plants such as cactus flowers.
Like the scale-feeding snout moth, Laetilia dilatifasciella, in its larval stage, is commonly known to feed on a wide variety of scale insects; however, this species tends to eat adult insects rather than the eggs and young. Another difference is that Laetilia dilatifasciella is usually less focused on consuming plants.
Like the previous two moth species, Laetilia zamacrella, a larva, is widely known to feed on scale insects (usually adults). However, this species differs from the other two. It primarily focuses on one specific species of scale insect: Toumeyella pinicola.
Baphala pallida also feed on scale insects in its larval stage. However, this species is different in that it primarily consumes scale insects of the families Kermesidae and Coccidae.
Euclemensia barksdalensis is a type of cosmet moth. These tiny moths act as parasites toward their host in their larval stage. In the case of this particular species, it is usually a parasite of a scale insect. Similar cosmet moths have similar dietary patterns, such as Euclemensia bassettella and Euclemensia schwarziella.
What Do Kermes Scale Moths Eat?
When they are larvae, Cryptothelea gloverii have been documented to follow a mixed diet of plants and insects. The most common plants they consume are their host plants’ fruit and foliage. Some examples of the host plants include avocados, the Jerusalem thorn, persimmon trees, and much more. They also eat the mites and scale insects of these host plants.
For the most part, in the larval stage, Lithophane antennata follows a herbivorous diet, mostly eating the leaves of certain trees and shrubs (e.g., cedar, juniper, etc.). However, in some cases, these larvae have been seen to consume the larvae of sawflies, winter moth caterpillars, and their own larvae siblings.
What Do Webbing Clothes Moths Eat?
When they are larvae, webbing clothes moths mainly consume animal products, such as wool and feathers. They have also been documented to eat the carcasses of insects and hair, flour, and more.
What Do Sooty-winged Chalcoela Moths Eat?
In their caterpillar stage, the sooty-winged chalcoela, a North American species, is widely known to consume the larvae of paper wasps.

What Do Pegasus Chalcoela Moths Eat?
Like their sooty-winged counterpart, in the caterpillar stage, the pegasus chalcoela, also a North American species, is widely known to consume the larvae of paper wasps.
It is also common for pegasus chalcoela caterpillars to pupate within the nests of these wasps. This species’ caterpillars also sometimes make webbing within the wasp nests and reside in them during the winter.
Calyptra bicolor is an Asian moth most commonly found in China and Japan; like many other species in the Calyptra genus, it is known as a vampire moth. This is because it can use its barbed proboscis (a long feeding tube attached to its head) to suck the blood of humans and large animals.
Calyptra bicolor is an Asian moth species most commonly found in Sri Lanka and Malaysia. This species is also a vampire moth that feeds on blood from humans and other large mammals. Calyptra fasciata is another vampire moth from India with the same dietary pattern.
Calyptra minuticornis is a moth species found all over Asia and Australia. As a vampire moth, the species latch onto buffalo and other relatively large mammals to suck out their blood in natural habitats.
Calyptra fasciata is a moth species in the East Indies. It is commonly known as a vampire moth, meaning it can use its barbed proboscis to suck the blood of humans and animals.
Calyptra parva is a moth species found in India. These vampire moths use their barbed proboscis to suck the blood of humans and animals. Calyptra pseudobicolor, under the same genus, is another moth species have the same dietary pattern as Calyptra parva.
Calyptra thalictriis is a moth species found all over Asia and certain parts of Europe. The species latch onto relatively large mammals to feed on their blood in natural habitats as vampire moths. But this species is generally thought not to attack humans very often.
What Do Corn Earworms Eat?
The corn earworm is widely known for being a huge agricultural pest. This is because, during their larval stage, they often take field crops, such as corn, tomato, cotton, and much more, as their hosts and feed on them.

What Do Tobacco Budworms Eat?
Like the corn earworm, the tobacco budworm is also commonly known as a disruptive agricultural pest, often taking tobacco and cotton plants as their host and eating them (though other crops are also sometimes chosen).
Additionally, the tobacco budworm also sometimes engages in cannibalism during the larvae stage; however, they are not as aggressive as the corn earworm larvae are.
What Do Fall Armyworm Moths Eat?
The fall armyworm moth is also a crop-disrupter, taking on a wide variety of plants as hosts and consuming them (e.g., barley, buckwheat, cotton, sugarcane, etc.).
However, it’s important to note that the larvae of this species are also known to engage in cannibalistic behavior when they can’t find enough food.
What Do Bertha Armyworms Eat?
Bertha armyworms, a moth species primarily found alongside western North America, is known as one of the biggest pests of canola in Canada.
Specifically, during the larval stage, this species often takes on canola plants as their host other plants are also sometimes used) and feeds on them, usually leading to substantial financial losses. These larvae have also been documented to engage in cannibalism in certain situations.
What Do Salt Marsh Moths Eat?
Salt marsh moths, when they are larvae, are primarily known to take on weedy plants like ground cherry, milkweed, pigweed, and more, as hosts and feed on them. They are also crop disruptors, commonly feeding on fruit and vegetable crops and tobacco.
This species of moth has been documented to engage in cannibalism during their larval stage.
What Do Isabella Tiger Moths Eat?
In the caterpillar stage, the Isabella Tiger Moth, an American species, diet is mainly plant-based, consisting of grass, leaves, and more. However, in specific circumstances, they can engage in cannibalistic behavior.
What Do Rattlebox Moths Eat?
Rattlebox moths, a species native to North and South America, often take on plants in the Crotalaria genus as hosts and feed on them in their larval stage. However, the hosts such as elm trees, bush clovers, fireweed, and much more can also be used.
Additionally, this moth species sometimes engages in cannibalism; specifically, the larvae have been documented to consume the other larvae, pupa, and even eggs of the same species!
What Do Hyposmocoma molluscivora moths Eat?
Hyposmocoma molluscivora, a moth, found exclusively in Hawaii, has been documented to eat snails in their larval stage. To do this, they produce a special type of silk that allows them to capture the snails and then eat them alive. For the most part, this species eats snails of the Tornatellides genus.

- This moth mainly consumes the plants of the oak species.
- The oak vegetation examples that the orange-striped oak worm moth feeds on are maple, birch, and hickory.
When Do Moths Eat?
A majority of the moth species are nocturnal, meaning they are active and come out to eat at night. A few moth species are active during the day, so they will be found eating during the daylight hours.
How Often Do Moths Eat?
Moth larvae are the most gluttonous eaters compared to adult moths. After morphing into adults, most moth species do not eat at all.
- Many of these adult moths die soon after mating. Moth larvae eat as often as possible and mostly large quantities of food immediately after birth. They proceed with this trend for a few days after.
- These larvae feed, depending on their sizes, will eat more food per day. The main goal of consuming too much food is to ensure that they grow in size to sustain themselves during the pupal stage.
What Eats Moths?
Moths are abundant, making them critical players at the bottom of the food chain, considering that they are a great source of nutrients to many organisms that rely on them for food.
Examples of organisms that feed on moths include but are not limited to bats, some bird species like owls, sparrows, lizards, cats, dogs, bears, some rodents, and amphibians.
Do Moths Predate on Humans?
Moths do not predate humans. A majority of the adult forms lack mouthparts.
- Some of the harm they exert on humans is causing allergic reactions in sensitive individuals, mainly because of their wings.
What Role Do Moths play in the Animal Food Chain?
Moths play an instrumental role at the bottom of the animal food chain because of their abundance.
- The different lifecycle stages of moths are an essential food source for most animals, such as bats, amphibians, small mammals, and nesting birds.
- They are a terrific food source for nutrients like calcium, iron, and zinc for the organisms that consume them. In this sense, moths play an excellent role as indicator species, giving clues about our environment’s health.
This implies that their absence or a massive decline in their numbers indicates a compromised ecosystem.
