Do Butterflies breathe?
Do butterflies breathe? The short answer is yes. Butterflies breathe through tiny pores in their body called Spiracles. These spiracles are present all over the butterfly’s body, mainly in the exoskeleton. Also, the butterflies have tracheal tubes that carry oxygen all over the body, which is why a butterfly is said to have passive respiration.
Do Butterflies have respiratory organs?
Butterflies do not have lungs or noses like human beings. They breathe through spiracles, and each Spiracle has a trachea, a tiny tube that takes oxygen and expels carbon dioxide. Spiracles are present all over the body of a butterfly but are mainly located on the abdomen area.

Where are these spiracles?
Spiracles are present all over the body of a butterfly but are mainly located on the abdomen area on the external Skelton, also called the exoskeleton.
Insects have a double membrane between their body and the skin. The membrane comprises two layers: an outer layer of hairs (the cuticle) and an inner layer of smaller hairs that make up the exoskeleton. The exoskeleton has no blood supply, so the insect keeps its fluids warm by shivering or vibrating its muscles. It pumps fluid from its abdomen to its thorax and head to cool down.
The outer skin has spiracles that allow the butterfly to breathe and act as a respiratory organ. When a butterfly is flying, its spiracles open up, thus allowing it to breathe, and these spiracles are connected to the tracheal tubes.
What are Tracheal tubes?
Tracheal tubes are found all over the body of the butterfly. They carry oxygen to all the parts of the body. Since oxygen can’t be transferred through blood (as their blood is a watery and yellowish liquid and does not contain hemoglobin, thus making the process of carrying oxygen impossible) in insects, these tracheal tubes are the only way for oxygen to be taken into the body.
Butterflies do not use active respiration as active respiration requires using specialized muscles to breathe, which butterflies do not have, and that’s why the butterfly’s respiration is called passive in science terms.
How do butterflies smell?
One of the most popular questions asked about butterflies is, “How do they smell?” Butterflies do not have a nose. Instead, they use their incredibly sensitive antennae to sense things around them, especially smells.
The antennae are responsible for detecting all kinds of stuff, including pheromones, scents, and chemicals in the air. The shape of a butterfly’s antennae allows them to pick up fragrances from tiny molecules in the air. These molecules are so small that insects can only smell them like butterflies and bees.
How do monarch butterflies breathe?
Like all other butterflies, monarchs also breathe through their spiracles. The spiracles are in their cuticle.
Monarchs, like most butterflies, breath through a series of small holes called spiracles. These holes are located on the sides of the body between their legs and wings.
Monarchs have three pairs of legs on their thorax. Their legs are covered in fine hairs. The large pair of front legs has a hooked tip that can help the butterfly to hold onto slippery surfaces and small branches.
Can butterflies breathe underwater?
We all know butterflies can flutter their wings and fly up into the sky, but can they swim like frogs? The answer is no. Butterflies cannot breathe underwater because they do not have gills. They need air to breathe, just like humans.
Sea snails, also called sea butterflies (which have wings), have a different respiratory system than insects. They have gills on their wings and can breathe underwater by extracting oxygen from them.
Conclusion:
In conclusion, butterflies breathe air through a special organ in their body called the Spiracles, which works much like the human lungs. Butterflies are covered with tiny holes called “pores” that they use to breathe through their skin when they are in the chrysalis. When butterflies exhale carbon dioxide, water vapor, and oxygen gas, their mouths do not move as they do with humans.
