Do Butterflies Eat Meat?

Butterflies are herbivore insects but are also observed consuming other food items if there is food scarcity and the flowers and plants are not producing enough nectar to fulfill their energy needs. They are innocent insects and do not cause harm to humans, animals, and birds until they digest the poisonous ones.

Do Butterflies Eat Meat? Some butterflies can eat meat because it provides protein, minerals, salt, and iron, allowing diversity in their diet. Moreover, the smell of rotting meat also attracts these insects. They can eat the rotting and decomposing flesh of various animals and insects because they lick the salts and cannot chew through the meat. Harvester, Blue Morph, and Emperor butterflies can feed on meat.

Some of them eat the poisonous sap from plant leaves and use it as a defense mechanism to protect themselves from predators. They are classified into various genera and behave differently in changing situations.

Why do butterflies eat meat?

Not all butterflies eat meat, but some species can consume the rotting or fresh flesh of various animals, birds, and insects. They live in wild and urban areas where they can get a chance to eat the meat of dead animals.

Protein and minerals

Protein and minerals are essential for all living organisms to maintain a healthy life and get the required energy for various activities.

Some butterfly species build protein in their bodies from amino acids and the nectar they drink from various flowers and plants.

Meat provides protein and essential minerals they need to survive because the deficiency of these nutrients can cause problems for these insects, and they cannot fly properly.

They need more protein in their diet in the caterpillar stage because they are developing many body parts and wing structures in this metamorphosis phase.

Their wings are made of a protein known as chitin, and they need amino acids, vitamins, and minerals from various eatables for better growth and healthy wing structure.

Diversity in diet

They usually feed on the nectar from flowers and plant sap to fill their stomach and get energy in their bodies. They are attracted to sugary substances and other healthy food items because they like to taste different eatables.

They fly from one place to another and forage for food. The caterpillars prefer to consume a more diverse diet than adult butterflies because they have mandibles and can sting into hard food items.

Meat is also an attractive food source for many adult butterflies and caterpillars. They can feed on many liquid food sources because they have tube-like mouthparts and suck the liquid in their body to get energy.

Rotting flesh becomes juicy over time, and they siphon the liquid over it to taste something different from flowers and plants’ nectar.

Provides salt and iron

Meat provides salt and iron to these insects, which acts as fuel to their flying capabilities, and they can cover long distances with more energy.

They do not get enough salt or sodium from the nectar they drink; therefore, they seek other food sources to consume enough sodium in their diet.

The female butterflies lose much sodium or salt from their bodies when they lay eggs, and the male loses sodium when mating with a female.

In addition, they need salt for successful mating and reproduction, which causes them to feed on meat and rotting flesh of dead animals and birds.

They get traces of iron from their diet, such as flower nectar and the liquid in the flesh, and spend a healthy life until they live.

Attracted to its smell

Butterflies have five senses, and the sense of smell is one of the most essential ones because they find their food source from the odor of flowers.

They have antennas that help them detect the food by its smell. These antennas have chemoreceptors to sense the food source and the chemicals released by males called pheromones.

They can go for rotting meat due to its sharp odor and gather around it for the juicy liquid. They fly to different places and sit on the food source with their sense of smell. 

Nutritional balance

Nutritional balance is essential for all insects because their bodies are designed to consume an adequate quantity of all food items and get sick if they lack some minerals and nutrients.

Sometimes, flower nectar is not a sufficient source of nutrition for these insects, and they fly to other food sources to get enough energy to fly and mate.

The nutrients in meat allow a better balance in their diet, and they get enough energy to find mates, reproduce, and forage food.

Nutrient imbalance and lack of salt and water cause health problems, and they cannot live a long and healthy life, especially in the wild, because they are more prone to predators in the forest.

What type of meat do butterflies eat?

Some butterfly species and caterpillars can feed on scale insects, rotting flesh of animals and birds, and juice or blood from meat.

They do not have teeth and suck the liquid food from the rotting meat because it becomes juicy when left in an open environment for a long time.

The microorganism, such as bacteria, start their action to break the tissues and cause the meat to rot over time. They lick the liquid from the flesh and fly away after getting enough nutrients.

They cannot eat the hard and preserved meat because they cannot chew through the flesh. The decomposition reaction causes dead bodies to rot and produce a sharp, foul smell, which attracts many insects and birds to consume it.

Are butterflies attracted to dead animals and insects?

Butterflies are attracted to dead animals and insects because the rotting flesh offers various minerals and nutrients to these insects.

They are attracted to dimethyl sulfide (DMS), which is present in the rotting flesh of dead animals and insects.

I saw some butterflies roaming around and sitting on the dead animal carcass, and I found after research that they take the sodium from the dead carcass.

Researchers found these insects are fans of rotting flesh of animal carcasses, and entomologists use baits for butterflies to trap them. 

A report about butterfly traps illustrated that the pieces of chicken and dead snake bodies are placed and changed daily to attract more insects.

The dead animal and bird carcasses release specific chemicals, and many insects are attracted to these chemicals.

What butterflies can eat meat?

Not all butterflies show this behavior to consume the minerals and salts from meat because the diet of each species can vary from others, depending on the habitat and the food sources available.

Harvester butterflies are famous for consuming the flesh of dead animals and insects, and they are the only butterfly species in North America to feed on such food items.

The Harvester caterpillars can eat small insects, such as aphids, and in adulthood, they prefer to feed on plants infested with aphids.

Moreover, Blue Morph and Purple Emperor butterflies also siphon the juicy liquid from rotting flesh. Purple Emperor prefers to eat other food items rather than flower nectar and sap in trees.

How often do butterflies eat meat?

It is usually not a common behavior of the insects to consume meat if other food sources are available, such as nectar-rich flowers, vegetables, and fruit plants.

They can feed on the meat if there is a food shortage, and they cannot forage food due to environmental conditions.

The flowers do not produce nectar in some seasons, and butterflies can search for other healthy food items to maintain their energy.

Once, I placed a piece of meat in my garden to observe the behavior of butterflies. I noticed they were not attracted to the fresh meat and remained busy collecting nectar from flowers.

It showed that it is not usual for these insects to consume meat if they have better options because their natural diet is nectar and sap from flowers and plants.
