Butterflies are nectar-feeding insects and cannot chew or consume solid food because they lack teeth. They use their proboscis to siphon the nectar and get the essential nutrients. Moreover, some of their species have a weird diet, as they eat pollen, urine, sweat, and animal dung because they have general adaptations according to their habitat and survival techniques.
Do Butterflies Eat Pollen? Most butterflies do not eat pollen because they only feed the nectar using their proboscis and are attracted to nectar-rich plants. However, some of their species, like the members of the Heliconius genus, like Zebra longwing, Red postman, Heliconius cydno, Heliconius heurippa, Heliconius elevatus, and Heliconius doris can eat it.
Their main focus is not to feed on the nectar-rich plants but to gather the minerals and salts to maintain their lifestyle and health.
Can butterflies eat pollen?
They usually do not like pollen because their mouthparts cannot chew and consume solid foods.
They forage the nectar-rich flowers around their habitat and can feed on the fruit juices and other liquid diets because they have a tube-like tongue to suck the nectar.
They can help the flowering plants in transferring pollen from one place to another, but it is not a common behavior to feed on them.
However, my friend studied many butterfly species and told me some species are adapted to feed on the anthers of different flowers.
I was astounded to hear that because I never knew about the pollen-feeding habit of these insects.
Why do some butterflies eat pollen?
Different butterfly species show varying behavior depending on their habitat and adaptations. They develop the habits necessary for survival and overcome the problems to thrive there.
Egg production
Some of their species eat pollen because they provide the essential amino acids missing in the flower nectar.
The amino acids also help the female butterflies in egg production.
I really love to study the details of their feeding habits and foraging behavior because they always attract my attention and give positive vibes.
Once, I saw a butterfly feeding on the grainy particles from the flower corolla, and I was surprised to see this. I researched this feeding behavior and learned that some species eat them to produce healthy eggs, as it is rich in protein and amino acids.
Moreover, I studied in a research paper that female species are more attracted to feed on them than males. However, they help the male improve the spermatophore quality and successful mating.
Longer lifespan
The research concluded that the butterfly species feeding on the pollen have longer lifespans, such as they live up to six to seven months.
However, the nectar-feeding species can last for a few weeks. The researchers concluded that the high amino acid content in anther may contribute to the enhanced lifespan, but the results are not statistically quantified.
However, they noticed that an increased lifespan is observed in some species.
In addition, the scientists raised another concept about the longevity of the fruit-feeding butterflies because they also have more amino acid intake.
Poison formation
Some of them eat it because the grainy stuff in specific flowering plants helps these insects to generate or produce a chemical called cyanide.
The chemical cyanide is poisonous for many animals, insects, and birds and helps the butterflies protect themselves against predators.
Once, my brother told me about the poisonous nature of some butterflies that are attracted to pollen.
He said they store the poisonous chemicals after eating the grainy stuff inside the flowers, and the predators last for 2-3 hours after consuming these poisonous insects.
The cyanide attacks the respiratory system, muscles, and heart, and they cannot withstand this chemical for more than a few hours.
Therefore, they feed on these tiny grain particles and develop a defense mechanism to deter predators, as the predators do not approach them after a bad experience.
Natural adaptation
All of these species have specialized adaptations to survive in their habitat because they cannot thrive longer without proper food and energy levels in their bodies.
Therefore, it is their natural adaptation to forage the pollen-rich flowers and feed on the grain particles in flowers and nectar to get energy and nutrients.
These flowers have long tubes-like corolla, and a few butterflies can collect and feed them to transfer the grainy stuff to other places.
What type of butterflies can eat pollen?
Members of the Heliconius genus are adapted to eat the pollen because they get various benefits from feeding from these plants.
For example, Zebra longwing, Red postman butterflies, Heliconius cydno, Heliconius heurippa, Heliconius elevatus, Heliconius doris, and many more species from this genus can eat it.
They usually flock together at night, and the poisonous nature helps them protect themselves at the cost of some fellows because predators die soon when they eat a few insects.
Some species do not intentionally seek the grainy stuff and consume them when feeding the nectar from the flowers.
They are found in different regions of America, as Zebra longwing butterflies are present in Mexico and Central America.
How do butterflies eat pollen?
The species from the Heliconius genus forage the pollen-rich flowers and use their long proboscis to suck the nectar.
They collect the pollen outside the proboscis and release the stomach enzymes to break down and liquefy the grainy particles.
Once, my neighbor told me that he observed the Zebra longwing butterflies in his yard, collecting the pollen grains and sucking the liquid from them after breaking them with their saliva.
He said these species can slurp the liquid from the grain particles outside their proboscis without problems and increase the energy levels to mate and reproduce.
Moreover, they collect grainy particles from limited plants because they need to produce the poison and prefer to feed on a specific plant.
These species have specialized proboscis to probe into the flower and collect them, while other insects do not have the mouthpart to get deep into the flower corolla.
What happens if butterflies accidentally eat pollen?
Most butterfly species are not adapted to feed on the grain particles inside the flowers because their tongues or proboscis cannot reach the deep flower parts.
Therefore, these species can accidentally consume the grain particles while sucking the nectar from plants, and the large number of pollen can cause the proboscis to block.
They cannot draw the nectar with the clogged proboscis and unzip the two halves to remove the blocking particles, as their tongue forms by combining the two parts after emerging from the chrysalis stage.
They use the saliva to assemble or zip the two halves again and suck the liquid from flowers without clogging.
Do butterflies collect pollen?
They do not intentionally collect pollen to help flowers in pollination, but the grain particles get attached to their legs and mouthpart when feeding on the nectar.
They disperse these to other flowers when flying from one place to another and play a role in pollination.
They do not compete with bees in collecting pollen because bees eat and carry them for their young ones. Moreover, their body lacks the specialized structures to gather them; therefore, butterflies do not transfer as many grain particles as other pollinating insects.
