Butterflies respond when you touch or try to hold them as they flutter their wings and struggle to escape this place. This behavior causes people to think that they feel pain in their wings and body, which is not true.
Can Butterflies Feel Pain? Butterflies do not feel pain because they lack the complex and essential nervous system and pain receptors to experience this physical sensation and brain nerves response to healing. Moreover, they have a sensory system and feel the touch or discomfort, as their brain only responds to the feeling of touch.
They do not feel and experience the same emotions and feelings that humans and many animals feel because their anatomy and body systems are different. Their anatomy and nervous system are designed according to their habitat and survival needs.
Why butterflies do not feel pain?
They do not experience pain and many other emotions, as they lack essential organs and receptors that work for this purpose.
Lack of pain receptors
The pain receptors are nerve-ending neurons in the nociceptors that catch the signals from the damaged tissues and respond to the chemicals the brain releases for healing.
These receptors are found in the spinal system, and these insects do not have backbones. I studied the feelings and emotions of these insects because my friend told me about many incidents where he noticed that these insects do not have feelings of pain.
I studied that they do not have pain receptors and backbone because they have the system of subesophageal ganglion.
I also read some incidents reported by many butterfly enthusiasts where they noticed that these flying insects can survive with broken wings and damaged abdomens without a lifestyle change.
I was surprised to study that several dozen butterflies on a farm were observed with damaged abdomens due to attacks from mice, and they were flying, eating, and mating without problems.
The only difference noted was in their landing because they lose balance when they land on the ground or plants to feed due to a missing part of their abdomen.
It shows that they do not feel aches if they get injured or damage their body parts, but it can affect their activities or reduce their lifespan.
They will respond immediately and need time to heal like humans if they get an injury on their abdomen if they possess pain receptors, but they carry on flying due to a lack of these receptors.
Sensory system
Butterflies have five senses, like humans and animals: taste, touch, hear, see, and smell. They have chemoreceptors in their feet and antennas and thermoreceptors in their wings, which help them detect the touch of something and temperature in their surroundings.
They have sensory organs, which help them navigate and sense changes in their surroundings. They experience the things, but it does not involve the pain or emotions.
They respond according to their senses and are the reflex actions needed to survive and overcome problems.
They feel physical sensations on their legs, feet, and antennas because of the scales and other receptors but do not go through aches.
Pain involves the emotional and sensory experience. Insects do not have a neurological system to decode and translate these feelings.
Less complex nervous system
They have a simple nervous system and can only handle and respond to functions like eating, mating, flying, and reproducing.
Once, my colleague told me many interesting facts about butterflies, and he said their nervous system is not located in the brain like humans.
I was astounded when he said that their nervous system is present in the thorax, and their nervous system can allow them to feel the touch.
Moreover, he explained that their nervous system involves learning, decoding, and understanding the changes around their surroundings rather than feeling pain.
It is a complex sensory feeling that needs thousands of nerves and receptors to provide signals to the brain and then the corresponding response to this physical sensation.
Do butterflies feel stress or emotions?
People often confuse the stress or discomfort of butterflies when they touch or hold them with pain. However, their nervous system allows them to sense the touch but does not include feelings like it.
They try to escape the place because they are sensitive and get stressed when humans and other organisms approach them.
Once, I tried to hold a butterfly from its wings, and it fluttered its wings so vigorously that I thought it was in stress. I asked my entomologist friend about this behavior, and he told me that these insects show behavioral responses to particular situations.
These sudden behaviors include fluttering their wings, trying to escape, and getting stressed, which does not have emotions and feelings like pain. It is more like a reaction than an emotion.
Their brain is more like allowing reflexes for positive and negative reactions rather than thinking and feeling emotions.
They feel the touch and, therefore, become stressed and fly away from the dangerous places or move towards their potential mates.
Does cutting a butterfly’s wings hurt?
Butterflies have several veins and nerves in their wings, which do not contain blood but are air-filled. These nerves are made of collagens and tissues, which provide structural support to their flying parts.
They detect the changes in air current around them if the leaf moves or their wings are touched, as they have hair and scales on their wings.
Moreover, the nerves send the impulses to muscles and other tiny nerves in their wings instead of the brain if you touch or cut the wing part.
It shows they do not feel pain in any body part, including their wings, if you cut them. However, the damage to wings can affect their flying patterns and activities.
Therefore, do not touch or hold them and avoid harming them, knowing they do not experience many emotions and feelings like pain.
For example, my friend told me that a team of specialized entomologists performed an experiment where they cut off the damaged wing part and glued the wing from another monarch butterfly.
He said the insect did not respond to the wing cutting and remained immobilized on the surface until the team members glued the wing and dried it.
He said he was surprised to see that the insect flew without problems and looked like it did not experience pain in this process.
Do butterfly caterpillars feel pain during the growing phases?
Caterpillars do not feel pain during their metamorphosis stages because it is a natural developing phenomenon.
People think that growing antennas, legs, and wings inside their bodies causes pain, but research and experiments show they do not experience aches in any life stage.
They struggle to overcome the changes and transitions in each stage and protect themselves but do not cause pain.
Scientists concluded that they may remember the experiences in their metamorphosis stages and try to avoid such incidents in the adult stage, as the nervous system in the caterpillar phase remains intact.
Not all caterpillars turn into butterflies, as some species face challenges and die due to environmental factors and predation risk.
How do butterflies survive evolution if they do not feel pain?
The evolution of these flying insects does not involve feelings of pain because they are adapted to survive without these emotions.
Not having pain receptors is favorable for them because it makes them survive longer and continue their life activities without delay.
Butterflies have short lifespans, and they will end up soon without completing their life purpose if they get injured and wait to heal, as aches will make them unfit and feel sick.
They do not have time for healing, as predators can attack and kill them. Moreover, the physical pain sensations will waste their time and keep them from mating, eating, and reproducing.
