If you were wondering about the diet of caterpillars that are frequently encountered in your garden, you have landed at the right feed. Caterpillars are found to consume different variety of food sources while mostly being herbivores.
Having known numerous species of caterpillars till this date, their diet also slightly varies from species to species. From understanding their dietary preferences to surprising facts about them in detail, you will be more familiar with the hungry caterpillars at the end of this article.
Caterpillars like to munch flower petals. Flowers contain sugar in high concentrations, and consuming sugary flower petals gives them quick energy. Your garden must have different types of flowers growing vibrantly; caterpillars might have been feeding on them.
Caterpillars find flowers a soft diet; softness is related to ease of chewing. Apart from sugar, some vitamins are also incorporated into ornamental flowers like marigolds, daisies, and so on.
You may have seen holes in the leaves of your garden plants, especially on the edges. Caterpillars are the leaf chewer and they like to feed on them for moisture and carbohydrates. But not all the plants provide them with the required water and energy, caterpillars mostly feed on milkweed, oak, and cabbage.
Many times, if you look closely, caterpillars are visible sliding around the branches and leaves of the host plants. Not only holes on the leaves, caterpillars feeding on them are also found to cause rolled leaves, webs, or skeletonizing the entire leaf.
Nature will find its way on its own. If you’ve let your garden overgrow, you must have seen wild grasses taking over the ground and surprisingly caterpillars feed on such grasses as well. This shows that there’s no way caterpillars remain hungry for longer periods.
Wild grasses are the most common food source of the caterpillars because they are readily and easily available to every part of the world. Some species of caterpillars are found to consume grasses because they are rather easy to digest while also getting carbohydrates.
Caterpillars seek a good amount of fiber in the stems of the host plants because fiber plays an important role in their digestion; in fact, fiber is found to support the entire digestion process of the caterpillars. The stems of the plants are rich in fiber and moisture.
Your garden might have different types of vegetables growing. Common vegetables may include tomatoes, cabbages, cucumbers, and so on, caterpillars are found to consume such vegetables and their stems. The stems of such vegetables provide enough moisture and essential nutrients for caterpillars.
The leaves of the nettle plant are another food source for many species of caterpillars. Although the plant possesses stings all over it caterpillars are found to be unaffected with it. This way while feeding on the stinging leaves, the caterpillars remain protected from the predators as well.
The consumption of stinging leaves is found to offer essential nutrients to the caterpillars because the leaves are rich in vitamins, minerals, iron, and chlorophyll. Many species of butterflies are often found flying around nettle plants seeking food and nutrients, making the plant one of the major food sources for not only the caterpillars but the entire wildlife.
Some species of caterpillars like to munch fruit rinds and they even lay their eggs on young fruit and flowers. Some of the common fruits are oranges, lemons, grapefruits, and watermelons on which caterpillars mostly attack for the sugars and antioxidants.
The ripe fruits are rather soft and therefore, caterpillars like to feed on both fruits and rinds of the selected fruits. Several species of butterflies are attracted to the watermelon rinds.
Well, honeycomb is a well-known bee element where bees are found to store honey and eggs. Some caterpillars are found to feed on the honeycomb as well. If you are someone who has a beehive around your house or yard and you are a beekeeper, caterpillars can cause pain in your business because they like to live in the honeycombs and eventually destroy it.
The honeycomb moth is one such caterpillar, also known as the waxworm, who especially forage for the honeycomb to lay eggs and feed on the sweet honey. These types of caterpillars have sweet tooth and are always eager for the honey.
The bark and twigs of the plants and trees are another potential food source for the caterpillars. More especially, woolly bear caterpillars, also known as fuzzy black caterpillars eat bark and twigs during hibernation in the winter for fiber. They are found to burrow within the leaves, bark, logs, and twigs during the winter.
Such caterpillars are not found to interfere with the living trees, it is only when they are cut that caterpillars jump into them to hibernate and consume. You should know that woolly bear caterpillars are the younger version or immature stage of the isabella tiger moth.
Although caterpillars are mostly herbivores, feeding on plant materials, some species of caterpillars are found to feed on animal waste as well. They relish chewing the dead skin of birds and animals, often considered nature’s cleaner.
Consuming carcasses is an excellent form of the natural ecosystem and caterpillars are happy they are a part of it. You should know that all of the caterpillars aren’t into carcasses, horn moths and skin moth caterpillars are two of the most popular caterpillars that like to feed on animal waste.
You might have heard about lady’s smock, a beautiful flowering plant. Cuckoo flower also goes by the name, lady’s smock, upon which some caterpillars like to feed. Especially, white butterflies are found to roam around this flower, feeding on seeds and flower petals, they also lay their eggs on the buds.
Cuckoo plants are found around the lowland and along the roadsides, thriving in damp soil, most commonly in the spring period. If your garden has such plants, orange-tip butterflies and green caterpillars are most probably lurking around.
The dietary preferences of caterpillars are not just limited to plants and their matters. They are found to feed on the trees as well. One such tree is Alder Buckthorn which offers beautiful flowers, twigs, and berries. Caterpillars like to consume both foliage and flowers of the tree.
The choice of Alder Buckthorn as one of the primary food sources of specific caterpillars suggests the wide variation of caterpillar’s diet choices. They are the consumer of the wide range of foods that are found in nature.
The vegetables in your garden could be another favorite of the caterpillars. Especially, they like to feed upon the leaves and stems of the vegetable crops that can be easily available in your garden. The herbivore caterpillars relish munching on soft and delicate veggies from which they also get required nutrients.
Popular vegetable crops may include cabbage, lettuce, broccoli, and so on, caterpillars may be abundantly found around such vegetable crops, constantly feeding on them for essential minerals.
Sometimes the period of easy access to primary food sources may lower for the caterpillars. In such conditions, they look for alternatives. In your garden, you might have been occasionally growing crops like carrots and radishes underground.
Caterpillars are mostly found to feed on the food that grows underground when above-ground food falls short. Such food items contain a significant amount of water and carbohydrates, upon which caterpillars like to feed occasionally and in a time of need.
Some species of butterflies are specifically dependent upon red ants as their primary source of diet. Such caterpillars are known to consume several hundreds of ants, their eggs, and larvae within a year.
What happens is, that the young caterpillars after feeding on the flowers drop to the ground appealing to the ants themselves. They are found to release some kind of odor in the surroundings and as a result,t ants carry the caterpillars into their nest, that’s when caterpillars feed on the pupae of the ants.
You must have seen birdsfoot trefoil around people's houses, roadsides, and along the meadows. Its leaves and flowers are one of the most popular foods for the caterpillars. Different species of butterflies and moths are found to roam around this plant for nectar and nutrients.
The bird foot trefoil showcases its majestic yellow flowers and is abundantly found around many parts of the world. In the world of caterpillars, this plant is a popular food plant providing essential nutrients for survival and vitality.
Moss and lichen are unique organisms that are prevalent around different parts of the world, mostly found in trees and rocks. Some caterpillars are known to feed on moss and lichen. Lichen is a combination of algae and fungi while moss is a plant but both are considered non-vascular organisms.
Well, it is surprising to hear that some species of caterpillars feed on each other. Yes, caterpillars can also be carnivores, feeding on one another in the time of need.
However, keep in mind that feeding on each other is an occasional case, it is not their part of primary food source but it projects the fact that caterpillars' diet is varied and they are naturally made to feed on a whole lot of food items.
Just like other living creatures of this natural world, caterpillars require food and hydration for survival. Not only that the nutrients from the food sources aid in all the major natural phenomena that undergoes in their life cycle. You should know that for every life cycle stage to pass, caterpillars need a balanced intake of diet.
Among different nutrition feeds, protein-rich food is the best for caterpillars in the time of growth and development. You should know that protein intake helps in the development of cells and tissues while also focusing on immune functions.
Further, caterpillars' diet consists of vitamins, minerals, and carbohydrates as well. Vitamin and mineral consumption has been found to look after the overall health of the caterpillars and carbohydrate intake is found to provide the required energy for motion and physical work.
The most important task of caterpillars is to eat. Feeding on food is vital throughout the growing period because food and energy are crucial for the metamorphosis. In the absence of the right nutrients and energy, caterpillars can't reach the adulthood stage healthily.
For several weeks, caterpillars are found to consume heavily. In the book, 3000 Facts about Animals, it has also been said that caterpillars can consume about 27,000 times the weight of the body during their entire lifetime.
It is quite surprising to hear that caterpillars feed on their eggshell as soon as they hatch from the egg. Eggshell is the outer covering of the egg which is found to be quite rich in protein. The new larva of the caterpillars initiates its life by feeding on the eggshell of their egg.
During their entire life, caterpillars spend most of their time eating. This is because they are in dire need of growth and development to reach adulthood which is only possible if they feed heavily. Further, they need to reserve energy if they are to complete every life stage, feeding constantly on a wide variety of food sources.
Several plants in the wild release toxic or unappealing odors in their surroundings as a defense mechanism to discourage herbivores from eating their foliage stems, flowers, and fruits. Surprisingly, caterpillars being notorious herbivores themselves, can hide those toxins in their own body without any harm and use them to protect themselves from predators.
Caterpillars possess mandibles that are jaws to consume food items. These jaws help them to chew plant matter and tough food sources. Since the dietary preferences of the caterpillars are vast, they are made to munch different types of food, from soft to quite hard.
Caterpillars in turn are the food for the birds. Different species of birds are found to feed on the caterpillars and they are also considered primary food source for many of them. Birds are found to get vital nutrients rich in protein and minerals from the consumption of caterpillars.

Another common predator of the caterpillars is beetles. Beetles are relatively larger but even the small ones (larvae) that are yet to reach the matured level are found to feed on the large caterpillars. This is possible because the beetles are equipped with large mandibles.
Well, wasps are surprisingly meat eater and they are found to hunt down caterpillars as their easy target to meet the energy demand. Some species of wasps are perfect carnivores, feeding on different types of insects including caterpillars.
If caterpillars come in the way of amphibians, they can happily hunt them down. Different invertebrates prefer munching caterpillars but amphibians may not quite easily reach out to the caterpillars because caterpillars are mostly found around vegetation.
You must have seen lizards and worms feeding on the caterpillars around your house or garden. Caterpillars are readily available around plants and vegetation, jumping into the opportunity, small reptiles relish consuming caterpillars for a good source of nutrients.
